Trask Big Sexy 2-Into-1 Exhaust For Harley Touring 2007-2016

Trask Big Sexy: The Heavyweight Champion of Performance Exhausts

When “standard” performance isn’t enough, the Trask Big Sexy 2-into-1 exhaust is the answer. For years, Trask Performance has been at the forefront of the Harley-Davidson turbo and high-compression scenes, and they have poured that racing DNA into the Big Sexy. Designed for 2007-2016 Harley-Davidson Touring models, this system is specifically tailored for riders who have moved beyond simple Stage I upgrades. If you have a high-compression Twin Cam or a large displacement engine (103″, 107″, or 110″+), the Big Sexy provides the volumetric efficiency required to unlock every last bit of torque and horsepower.

Dyno-Proven Architecture and Scavenging

The Big Sexy isn’t just about the name; it’s about the engineering. It features a unique, large-diameter header design that facilitates massive exhaust flow without the “choking” effect found in many street-legal pipes. The 2-into-1 configuration culminates in a high-velocity merged collector that creates a powerful scavenging effect. This vacuum-like pull ensures that spent exhaust gases are evacuated instantly, allowing the intake stroke to draw in a cleaner, more potent air-fuel mixture. The result is a dyno-proven power curve that offers a significant “seat-of-the-pants” difference in the mid-to-high RPM range, making it the perfect pipe for aggressive highway passing and light-to-light sprints.

Expert Installation & Tuning Insight

As experts in Performance Bagger builds, we consider the Big Sexy one of the best-sounding pipes on the market. Pro Tip: This is a “loud” pipe. While it has a deep, rhythmic rumble at idle, it produces a raw, thunderous roar under wide-open throttle. If you prioritize touring comfort and long-range intercom conversations, be prepared for a very present exhaust note. Tuning Warning: Because this system flows such a high volume of air, a professional dyno tune or a high-end auto-tuner (like the Dynojet Power Vision) is non-negotiable. Installation Note: To prevent “blueing” or discoloration on the chrome version, ensure the bike is properly tuned and that the headers are cleaned of all oils and debris before the first fire-up.

The Signature Trask Performance Look

The Big Sexy doesn’t just perform; it makes a statement. The system includes full-coverage heat shields that maintain a clean look while protecting your boots and legs from the intense heat generated by high-output motors. The signature Trask end cap provides a subtle, high-end finish that sets your bike apart from the sea of standard slip-ons. It offers excellent ground clearance for those who like to lean their Road Glide or Street Glide into the corners, making it a functional upgrade for the modern performance-minded rider.

Fitment Note: Fits 2007-2016 Touring models. May require a spacer for certain aftermarket floorboard setups or extended side covers.
