TRASK 2-into-1 Big Sexy Exhaust System - Polished Stainless Steel TM-5120PO

If you're running big power through a Twin Cam engine, exhaust flow is where gains are made or left on the table. The TRASK 2-into-1 Big Sexy consolidates exhaust gases through a high-flow merge design and optimized muffler, reducing backpressure while maintaining scavenging efficiency. Built from mandrel-bent stainless steel with precision engineering throughout, this system delivers measurable horsepower increases without compromising durability or aesthetics.

Engineered specifically for Twin Cam applications, the Big Sexy features a 3-step header that optimizes flow across the RPM band, a double slip joint for thermal expansion, and a custom assault-style heat shield that looks as aggressive as it performs. Made in the U.S.A. by TRASK, this is a serious upgrade for builders and racers who demand reliability at high output levels.
