The 27WON design is about performance and exhaust note without compromise. Made for both the FC1 (sedan) and FC3 (coupe), 27won's unique catback combines three resonator styles to create an exhaust system that growls when you mash the throttle but purrs during the drive to work and long road trips.

The single resonator features two design styles inside. An absorption resonator and expansion chamber resonator. These act to remove low and high frequencies and allow the exhaust gases to pass straight through.

Every 27WON Exhaust System is made from T304 Stainless Steel tubing that is CNC mandrel bent and precision TIG welded for a long lasting and durable performance part.

All 27WON Exhaust systems feature strong 11mm thick 3-bolt flanges for optimal sealing and perfect alignment during installation. Unlike band-clamps or traditional 2 bolt horizontal flanges, the 27WON 3-bolt flanges will not leak over time. Paired with the custom in house designed multi-layer steel gaskets and you get a long lasting worry free system.

There are absolutely no compromises with the 27WON Performance Exhaust, not even the bolts and nuts. Every exhaust system comes with 100% stainless steel hardware and multi-layer SS gaskets.

You talked and 27WON listened. After a year on the market 27won took customer feedback and now offer a dual round tip version for those who want a more classic exhaust look. The dual tip system has the same precision crafted performance and is a more budget friendly option.
