Sin for the Civic. Presenting the AWE Exhaust Suite for the Honda FC1/FC3 Civic Si. At the intersection of sophistication and aggression lies the Touring Edition Exhaust. A 3" T304L stainless steel downpipe-back configuration, the Touring Edition Exhaust is the perfect dose of steel for drivers looking for straight-pipe performance, a deep, sophisticated exhaust note, and zero drone at highway speeds. Featuring an integrated front pipe, bespoke mid pipe resonator, and AWE's patented drone-canceling solution, 180 Technology, the Touring Edition delivers a full-bodied, rasp-free L15 soundtrack unachieved by any of its peers. Under boost and heavy throttle, the Touring Edition screams. At highway speeds, drone-free within the cabin - the best of both worlds. Perfectly engineered and packaged for the FC1/FC3 Civic Si, all backed by AWE No CEL and Perfect Fitment Guarantees. Conversion kits: AWE made it easy to convert between Track and Touring Editions, as well as dual and triple tip configurations, if you decide at a later date to change your volume or the aesthetic. Important fitment notes The Touring and Track Edition Exhausts include a 3" front pipe that is designed and sized accordingly to mate to the factory downpipe or any downpipe designed to mate to the factory exhaust. This front pipe is integrated into the design of the exhausts. AWE exhausts are not designed to mate with other aftermarket front pipes. We decided to reuse the factory-style flange and gasket for reliability and long-term performance. The factory's double-layer steel gasket design is vastly superior to any aftermarket flat gasket. This design allows for the gasket to be fully captured by the machined groove in the flange, eliminating any possibility of blowout or deterioration over long-term use. Additionally, it is fully serviceable, unlike a flat gasket that can stick to the mating flanges and tear upon removal.

Tip Options:Each exhaust comes complete with 4.5" double-walled, slash-cut tips available in chrome silver or diamond black, and feature a stamped AWE logo. All tips are individually adjustable, allowing depth into the bumper to be set according to personal taste. The Touring Edition Exhausts feature a modular tip design that allows drivers the choice of running double or triple 4.5" slash-cut tips via our bespoke stamped tip merges. With such interchangeability, a dual tip configuration can be converted into a tri-tip configuration (and vice-versa) within minutes via an AWE Tip Conversion Kit.

AWE's patented 180 Technology works a little something like this: As exhaust gases exit the engine and flow into an AWE 180 Technology-equipped resonator, they pass through strategically located ports, and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. Depending on the sound requirements of each vehicle, AWE acoustic engineers adjust the size and location of the ports and the chambers. By controlling the size and location of these key elements, we also control when the sound waves exit the chambers. The specific timing of when the reflected sound waves re-join the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies. AWE 180 Technology is not on a one size fits all" concept. Rather, AWE engineers design sound cancelation resonators based upon the specific acoustics generated by vehicle types, thereby ensuring perfect sound, every time. It's one of the reasons AWE exhausts have earned a reputation for the perfect tone, regardless of application. The result? The removal of unwanted tones in all AWE 180 Technology-equipped exhaust systems. The sound produced by this formula is the perfect, signature note. Unlocked performance and spot-on tone, every time.
