Subaru WRX STI Cat-Back Exhaust made by Mishimoto

One of the biggest complaints we hear especially from 2015 WRX owners is that the stock set up doesn't have any aggressive exhaust notes. Mishimoto is here to fix that and give a more aggressive exhaust note for both the WRX and STI line up!

Allowing a smooth exhaust flow from the 3" piping followed by 2.25" y-mufflers and finished off with quad 3.5" tips! Giving a much more aggressive exhaust note while also increasing a dyno proven 9 whp and 8wtq (93 octane 2015 CVT WRX) while keeping safe air to fuel ratios!

Fits both EJ257 and FA20DIT engine codes. All hardware is included with this kit with general install time being under an hour!

Proudly made in the USA and backed by Mishimoto's Limited Lifetime Warranty!
