Here at Mishimoto we've decided to expand our line of parts that fit the 2015 WRX. Mishimoto is proud to release the Cat-Back Exhaust for the 2015+ Subaru WRX/STI. One of the biggest complaints 2015 WRX owners have is that the stock 2015 WRX exhaust systems lack an aggressive tone. The Mishimoto Cat-Back Exhaust for the 2015 WRX allows the entire system to breathe easier, providing horsepower, torque, and a rich exhaust tone.
After comparing many different muffler sizes and designs, Mishimoto engineers chose oval mufflers to help prevent highway drone but still provide an aggressive exhaust tone for your 2015 WRX. During dyno pulls with the 2015 CVT WRX, Mishimoto saw gains of up to 9 whp and 8 wtq using 93 octane fuel while maintaining safe AFRs on a stock tune (see additional images for dyno chart). This exhaust installs in under one hour and features quad 3.5" staggered double wall polished tips. The Mishimoto Cat-Back Exhaust for the 2015 WRX provides an extremely aggressive turbo and exhaust tone under acceleration and boost, giving you that sweet sound you've been looking for!
The Mishimoto engineers designed this cat-back exhaust for the WRX and STI as a four-piece design, comprised of precision TIG-welded 304 stainless steel. This allows a smooth exhaust flow from the 3.0" 2-bolt exhaust flange all the way through the 2.25" Y-section. To top it off, this exhaust includes two 2.25" V-band clamps, a 3" exhaust-band clamp, a new 3" 2-bolt flange gasket, and all stainless steel hardware, so you don�t have to worry about rusty hardware! The Mishimoto Cat-Back Exhaust for the Subaru WRX, like all of our parts, comes with the Mishimoto Lifetime Warranty.
