2.75-Inch T304 Stainless Steel Cat-Back Exhaust

The 27WON exhaust is a front-pipe back system engineered to enhance the sound and performance of the 10th-generation Honda Accord (2018-2022) 1.5T and 2.0T Sedan models. Constructed from 2.75-inch T304 stainless steel piping with a premium brushed finish, this exhaust system features TIG welding at every connection for superior durability. It utilizes 3-bolt flanges with custom-matched gaskets to replace standard slip joints, ensuring a proper seal and alignment. This exhaust system is designed with dual-phase resonators, one on each side, which employ an expansion chamber and absorption resonator. This configuration effectively cancels both high and low frequencies, delivering a crisp, deep, and drone-free exhaust tone. The manufacturer notes that pairing this front-pipe-back exhaust with an aftermarket high-performance downpipe may increase noise, harshness, and vibration (NVH) and overall exhaust volume. For those seeking a full turbo-back setup, this combination might result in a louder system than some users prefer. Important fitment information: This exhaust is designed for the 2018 - 2022 Honda Accord 1.5T (Sedan CV1) and the 2018 - 2022 Honda Accord 2.0T (Sedan CV2). The included F.R.P. bumper shrouds should be painted or wrapped before installation to protect their finish and ensure longevity.
