Description
An easy to install axleback exhaust that fits the look and sound you want for your 15-21 WRX/STi. This 5 Inch Muffled bolt-up axleback exhaust will play the song of your people and look great with its 3 Inch Double Wall Tips. Direct from our welding bench and onto your car.
Limited Lifetime Warranty available to original purchaser. Covers defects in workmanship and material.
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.
Installation Instructions:
Installation Guide - Axleback/Catback/Midpipe
Recommended Add-Ons:
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

My setup is a Grimmspeed jpipe, Invidia R400 midpipe (resonator still installed) and Nameless muffler deletes of course. Here’s my cold start (with stratified start). I absolutely love the setup. Surprisingly quiet while cruising but when you get much more pops when downshifting and sometimes upshifting. I’ve been wanting these deletes for a while and I’m extremely happy with my purchase!
Axleback Exhaust - 2015-2021 WRX/STi Invidia Q300 / R400 / N1 Fit Replacement - Muffler Delete - 3.5" Single Wall Tips

Ok so, I have a 2009 wrx and I knew that this product would not be compatible without some modifications but went ahead and purchased anyways. Let me tell you, it was worth it. Didn't take much and super happy with the way it turned out. Will be making a custom plastic trim piece for the rear bumper to fit the nameless axle back, but for now it works. Would recommend if you're someone like me wanting the classic quad exhaust look and currently running a invidia system.

Listening intently as Subies pass by, trying to determine what instrument they’re using to create that beautiful rumble. Hours of watching reviews to help me with my decision. I needed to hear the UEL headers, as stock left me wanting more….but not too much to bug the boss at home or irritate the neighbors. Torn between 5” and 4” mufflers, I took the chance and ordered the 4” axle back. I waited patiently and when it arrived, I let it sit in my garage wondering how loud it would be, and if it would be too much. With the box opened, I unveiled a beautiful exhaust, with exceptional welds and high shine. I removed the stock and installed the Nameless. In my giddiness, I called my teenage sons to join me upon initial turn on. 3…2…1. “Grrrrrumblegrrrrumblerumble”…. Instant smiles…but zero regrets. “Not too quiet, not too loud, just right” In 1st thru 3rd the tone is low and deep…with zero raspiness. At highway speeds, no drone and just the right amount of rumble to not overpower radio and conversation. At idle at stop lights, quiet…until the green light awakens the motor…. Thanks for a great product. Smiles every day… Peace out…

Track pipe install was extremely easy. Bolts right up to the nameless midpipe. Sound is aggressive but not annoying. Really screams at WOT, but a nice hum and not overboard when daily driving. Another great performance and why I've been rocking with them since my first 2015 WRX. For what it's worth, my 2019 is equipped with the original turbo back exhaust I first bought for the first WRX and have moved from vehicle to vehicle. Nameless can't be beat.
