Mishimoto 3" Stainless Steel Cat-Back Exhaust - Subaru WRX / STi 2015-2021

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 2015 WRX exhaust installs in under one hour and features quad 3.5" staggered double wall polished tips. The Mishimoto 2015 WRX Cat-Back Exhaust 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 WRX and STI cat-back exhaust 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 2015 WRX 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!
