We all have different styles and want different things from our cars, some people like loud, some like flashy, some like to go largely unnoticed. Shopping for an exhaust isn’t always easy because we all look for different things and you are usually stuck with one option per manufacturer. So, we here at Nameless thought, why can’t we just make a system for one of the most popular Subaru’s out there that has options of everyone?
So we did! The Nameless Performance axleback exhaust system for the VA chassis Subaru STI from 2015-2018 and the Subaru WRX from 2015-2021 is fully configurable - check out the vehicle page for more configurations.
Our axle back fits the OEM midpipe at the Y. Removing the two large factory 13.5 lb restrictive baffled mufflers in lieu of a pair of mandrel bent, TIG welded, T304 stainless steel pipes and configurable tailpipe tip style, this system is easily configurable to your desired look and sound level with muffled and un-muffled (muffler delete) versions and a wide selection of various tip configurations.
Factory fit laser cut flanges and 2″ dual piping has equivalent flow characteristics of a 3" single straight pipe, providing excellent breathing characteristics for high end horsepower and generating an increase in low end torque (roughly 10 hp/11 ft lb at the wheels for this and the other muffled axleback options we offer).
Fits 2015-2018 STi and 2015-2021 WRX Sedans with OEM or OEM fitment (Nameless Performance) midpipe, not compatible with the STI (SPT) dealer installed midpipe. This will NOT fit the 2019 STI or the 2018 STi R/A.
Each axleback comes with a full hardware kit for installation.
Our urethane bushings hold your exhaust in place better that the factory rubber bushings and are highly recommended if you race your car or enjoy spirited driving. During hard cornering the exhaust "wags" left to right which sometimes causes the tips to touch the bumper. When this happens there is a chance your bumper can be damaged. The best way to avoid this is to use our urethane exhaust bushings to hold the exhaust in place.
- 2 Bushings: Replace the two bushings at the rear of the car closest to the bumper. Recommend for those who either drive hard on the street or race occasionally at the track.
- 4 Bushings: Replace all 4 rubber bushings on the axleback portion of the exhaust. Recommended for people who race their cars often.
- 5 Bushings: Replace all 5 of the factory rubber bushings from the midpipe back. Recommended for those who are hard core autocross or circuit racers.
Fits: 2015, 2016, 2017, 2018, 2019, 2020, 2021 Subaru WRX; 2015, 2016, 2017, 2018 Subaru STi
