This dense material withstands prolonged exposure to hot exhaust flow and highway vibration, maintaining a crisp, detailed surface finish over thousands of miles.

### Moto-Inspired Custom Detailing

The Moto Series design features longitudinal relief slots machined around the circumference of the cap, giving the rear end of your touring bagger a mechanical, race-ready look. The precision-milled Rinehart script adds an authentic signature touch that complements extended saddlebags and custom rear fills.

]]> Rinehart Racing HP 40 2-Into-1 Slip-On Muffler For Harley Softail (2025–2026)

High-Performance 4-Inch 2-Into-1 Acoustic & Power Upgrade for Milwaukee-Eight Softails

Unleash maximum mid-range torque, razor-sharp throttle response, and iconic sound from your factory 2-into-1 header with the Rinehart Racing HP 40 2-Into-1 Slip-On Muffler. Engineered specifically for 2025 and 2026 Harley-Davidson Softail models equipped with OEM single-sided 2-into-1 exhaust setups, the HP 40 transforms quiet stock performance into a deep, aggressive V-Twin roar.

Featuring a substantial 4-inch muffler canister paired with Rinehart’s race-proven internal baffle design, the HP 40 eliminates backpressure bottlenecks while accelerating exhaust gas velocity.

Acoustic Tuning & Power Performance

### The HP 40 Performance Core Advantage

Factory 2-into-1 mufflers on late-model Milwaukee-Eight Softails are designed with heavy baffle packing and internal restrictions that dampen sound and trap exhaust heat. Rinehart’s HP 40 core allows exhaust pulses to expand evenly through a high-velocity perforated core. This increases engine breathing efficiency, delivering immediate roll-on power and a crisp, resonant exhaust tone that comes alive when you crack the throttle.

### Key Advantages

    Maximum Torque Scavenging: Complements 2-into-1 collector pulses for noticeable low-to-mid range torque gains.
    Deep V-Twin Sound: Replaces factory whisper-quiet mufflers with Rinehart’s signature deep bass rumble.
    Billet End Cap Styling: CNC-machined end caps add an iconic custom finish to the rear quarter of your motorcycle.

Vehicle Compatibility Guide

Rinehart Racing HP 40 2-Into-1 Slip-On Mufflers are engineered for direct, 100% bolt-on installation on 2025–2026 Harley-Davidson Softail models equipped with stock 2-into-1 factory header pipes:

### Compatible Harley-Davidson Softail Models (2025–2026)

  • Fat Bob 114 / 117: FXFBS (2025–2026 equipped with 2-into-1 header configuration)

Fitment Note: Designed solely for models featuring a factory 2-into-1 head pipe assembly. Will not fit Softail models with dual staggered or 2-into-2 header pipes without a full header swap.

Step-by-Step DIY Installation Guide

Installing the Rinehart HP 40 2-Into-1 Slip-On Muffler on your Softail takes approximately 30 to 45 minutes using standard shop tools.

### Required Tools

  • 3/8″ Drive Ratchet with 1/2″ and 9/16″ sockets
  • Torx key set (T27 / T30)
  • Exhaust clamp tool or combination wrenches
  • Penetrating lubricant
  • Clean microfiber towel

### Step 1: Removal of Factory 2-Into-1 Muffler

Ensure the motorcycle is cool and supported securely. Apply a light film of penetrating oil around the single collector joint. Unbolt the rear mounting bolts securing the stock muffler canister to the frame support bracket. Loosen the factory exhaust clamp, then gently twist and slide the stock muffler rearward off the collector pipe.

### Step 2: Prepping Clamps & Alignment

Slide a new heavy-duty barrel exhaust clamp over the inlet expander joint of your new Rinehart HP 40 muffler. Apply a small amount of anti-seize or penetrating oil to the header collector tip for smooth sliding.

### Step 3: Mounting the Rinehart HP 40

Slide the Rinehart HP 40 muffler forward onto the collector pipe outlet until fully seated. Align the rear bracket mounting points with the chassis support frame. Finger-tighten the mounting bolts, check tip clearance and alignment, then torque all hardware and clamps to factory service specifications.

Frequently Asked Questions

### Is an ECU re-tune required when installing the Rinehart HP 40 Slip-On?

No. If you are keeping the stock air intake system and original 2-into-1 header pipe, an ECU re-tune is not strictly required. However, adding a high-flow air cleaner and an aftermarket tuner will maximize total horsepower and mid-range torque output.

### Will this muffler fit a Softail with dual staggered headers?

No. The HP 40 is engineered specifically as a single slip-on unit for Softail models running a 2-into-1 factory collector system. If your Softail has dual pipes, you will need standard Rinehart 3″ or 4″ dual slip-on mufflers.

Iconic V-Twin sound, performance, and custom billet styling.

]]> Rinehart Racing 4″ Slip-On Mufflers For Harley Freewheeler (2015–2016)

Signature Sound and Performance Tailored Specifically for the Freewheeler Trike

Elevate the power, response, and deep exhaust note of your Twin Cam trike with Rinehart Racing 4″ Slip-On Mufflers. Custom-engineered specifically for 2015 and 2016 Harley-Davidson Freewheeler (FLRT) models, these slip-on mufflers replace restrictive factory exhaust cans with Rinehart’s legendary race-proven baffle design, delivering a rich, throaty V-Twin rumble without harsh cabin rumble or highway drone.

Handcrafted in the USA from heavy-gauge steel, these 4-inch mufflers feature CNC-machined billet aluminum end caps and an optimized internal core length designed to match the unique body cutouts and exhaust length of the Freewheeler chassis. Experience improved low-end torque, cooler running temperatures, and a bold rear stance that complements your trike’s hot-rod style.

Engine Performance & Power Output

### Optimized Backpressure for Twin Cam 103 Engine

The 2015–2016 Harley-Davidson Freewheeler is powered by the high-output Twin Cam 103ci engine. Stock mufflers trap heat and create excessive backpressure, which chokes engine performance—especially under the heavier weight of a three-wheeled chassis. Rinehart’s 4″ slip-on mufflers feature a specially tuned performance baffle that improves exhaust gas scavenging, increasing torque where trikes need it most: right off the line and through mid-range acceleration.

### Key Performance Benefits

  • Horsepower & Torque Gains: Measurable gains across the entire powerband when replacing stock mufflers.
  • Lower Thermal Load: Improved exhaust velocity helps carry heat away from the rider and passenger area.
  • Deep V-Twin Acoustic: Delivers a deep bass tone at idle and a crisp, authoritative bark under hard acceleration.

Vehicle Compatibility Guide

Rinehart Racing 4″ Slip-On Mufflers (Part #500-0104 Chrome / #500-0105 Black) are engineered for direct, 100% bolt-on fitment on the 2015–2016 Harley-Davidson Freewheeler trike platform:

### Harley-Davidson Freewheeler Models (2015–2016)

  • Harley-Davidson Freewheeler: FLRT Twin Cam 103ci (2015)
  • Harley-Davidson Freewheeler: FLRT Twin Cam 103ci (2016)

Fitment Note: Engineered specifically for 2015–2016 Freewheeler trike models with factory head pipes. Will not fit two-wheeled Touring models or Milwaukee-Eight (2017+) engine setups without appropriate header adapters.

Step-by-Step DIY Installation Guide

Upgrading your Freewheeler trike exhaust to Rinehart 4″ Slip-Ons takes under 45 minutes using basic hand tools.

### Required Tools

  • 3/8″ Drive Ratchet with 1/2″ and 9/16″ sockets
  • Torca clamp tool or combination wrench set
  • Penetrating lubricant
  • Clean microfiber towel

### Step 1: Removal of Stock Freewheeler Mufflers

Ensure the engine and exhaust system are completely cool. Spray a light amount of penetrating oil onto the inlet joints of the factory mufflers. Remove the rear frame mounting bolts holding the stock mufflers under the rear body work. Loosen the exhaust pipe clamps at the head pipe connection, then gently twist and slide the stock mufflers rearward off the head pipes.

### Step 2: Preparing New Clamps & Alignment

Slide new 2-inch heavy-duty barrel exhaust clamps over the expansion inlets of your new Rinehart 4″ slip-ons. Align the inlet end over the stock head pipe outlets.

### Step 3: Mounting the Rinehart 4″ Mufflers

Slide the Rinehart mufflers forward onto the header pipes until fully seated. Align the rear bracket mounting points with the trike chassis frame mounts. Finger-tighten the rear mounting bolts, adjust the tips so they sit centered in the body openings, and torque all hardware and clamps to factory specs.

Frequently Asked Questions

### Do I need to re-tune my 2015–2016 Freewheeler after installing these slip-ons?

No. If your 2015–2016 Freewheeler has the stock air cleaner and factory head pipes, an ECU tune is not strictly required. However, adding a high-flow air intake and an aftermarket tuner will maximize power gains and optimize fuel-to-air ratios.

### Are these mufflers the same length as standard two-wheel Touring slip-ons?

No. Rinehart specifically designs Freewheeler slip-ons to match the exact rear body cutouts and shorter overall frame clearance of the FLRT trike chassis, ensuring a flush, factory-like appearance.

[The Ultimate Exhaust Solution for Stretched Bag Performance Bagger Builds]

]]> Rinehart 4 1/2″ HP45 XL Slip-On Mufflers For Harley Touring 2017-2026

Rinehart HP45 XL: Engineered for the Modern Stretched Bagger

The Rinehart 4 1/2″ HP45 XL Slip-On Mufflers are the definitive answer for 2017-2026 Harley-Davidson Touring riders who demand both peak performance and flawless visual proportions. As Harley-Davidson moved toward “Special,” “ST,” and “CVO” models with factory-stretched saddlebags, standard mufflers often appeared “sunken” or too short, leaving an awkward gap at the rear of the bike. The HP45 XL features an extended muffler body designed to sit flush with the end of the bags, providing a seamless, custom-shop silhouette. Compatible with the Road Glide, Street Glide, and Road King, these mufflers are built to handle the massive air-flow requirements of the 107, 114, 117, and 121 cubic inch Milwaukee-Eight engines, ensuring your bike looks as powerful as it performs.

Internal Volume and the DBX Performance Advantage

The “XL” in the name doesn’t just refer to the length; it also signifies an increase in internal resonance volume. By utilizing a 4.5-inch diameter body and an extended length, Rinehart has created more space for exhaust gases to expand. This extra volume, paired with the legendary DBX performance baffle, produces a sound that is noticeably deeper and “thumpier” than standard slip-ons. The DBX baffle is specifically tuned to eliminate the “tinny” or raspy high-pitched sounds that can plague high-flow M8 exhausts. Instead, it delivers a crisp, mechanical bark under load and a smooth, rhythmic low-frequency rumble at idle. This engineering ensures that while you get an aggressive sound, you maintain the necessary backpressure to keep your mid-range torque curve climbing.

Rinehart HP45 XL Technical Specifications

  • Fitment: 2017-2026 Harley-Davidson Touring (M8 Engines).
  • Design: Extended XL body length for factory or aftermarket stretched saddlebags.
  • Muffler Body: 4.5-inch 16-gauge steel with a high-velocity internal baffle.
  • Finish Options: Available in Show Chrome or Raven Black with contrast-cut end caps.
  • Sound Profile: High-output DBX baffle for a deep, aggressive roar.

Expert Tuning & Installation Advice

As V-Twin performance specialists, we’ve found the HP45 XL to be a favorite for those performing Stage II cam upgrades. Pro Tip: Because the XL body and DBX baffle significantly increase exhaust flow, your Milwaukee-Eight engine will require more fuel to stay within a safe operating temperature. We highly recommend a Vance & Hines Fuelpak FP4 or Dynojet Power Vision to properly calibrate your ECM. This prevents the “lean-burn” that causes headers to glow and chrome to blue. Installation Note: When mounting the HP45 XL, ensure your rubber muffler hangers are in good condition; the extra length of the XL body places slightly more leverage on the rear mounts. Always wipe the pipes down with denatured alcohol before the first start to prevent fingerprints from being permanently etched into the finish during the first heat cycle.

The Signature Rinehart Craftsmanship

Every Rinehart exhaust system is 100% Made in the USA and backed by their industry-leading reputation for quality. The HP45 XL is finished with CNC-machined billet aluminum end caps that add a premium, high-velocity look to your Bagger’s rear profile. Whether you are building a “Blacked-Out” ST-style performance bike or a classic “Chrome-and-Stretched” cruiser, the Rinehart HP45 XL provides the perfect blend of high-end aesthetics, massive sound depth, and dyno-proven results. It is the definitive choice for the rider who refuses to compromise on style or soul.

Fitment Note: Fits all 2017-2026 Touring models. Highly recommended for models with stretched saddlebags. Not compatible with Trike models.

Rinehart 4 1/2″ HP45XL Full Length Slip-Ons For Harley Touring

A striking, bold addition to the Rinehart Racing catalog of performance products, the HP45XL brings a fresh style and finish paired with race-inspired performance and power you’ve come to expect from Rinehart. Mufflers provide free-flowing exhaust while maintaining the perfect amount of back pressure, unlocking both horsepower and torque. Contrasting end caps are color-matched to pair perfectly with paints used by Harley Davidson on ST and Anniversary Touring models.

Similar in many ways to the 4.5″ HP45 Mufflers from Rinehart, HP45XL Slip-On Mufflers feature a longer silencer body that extends the end caps beyond the back of bike – as shown in product images.

Features:

  • Extended length slip-on performance muffler

The Rinehart 4″ DBX 40 Slip-On Mufflers for Harley-Davidson Touring and Trike (1995-2026) represents the pinnacle of streamlined exhaust architecture for the serious performance enthusiast. For the rider of a Road Glide, Street Glide, or Freewheeler who values the precision of a competition-grade “DBX” signature as much as long-term structural durability, the challenge has always been finding a muffler system that bridges the gap between raw, high-decibel flow and elite factory-integrated aesthetics.
