 Product Description

Designed for the VA Chassis (2015-2018) Subaru WRX and STi Sedans, the Nameless Performance AxleBack Exhaust is a direct factory fit to the OEM midpipe at the Y. Removing the two factory 13.5lb 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.

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 10hp/11ft lb at the wheels for this and the other muffled axleback options we offer).

Fits 2015-2018 WRX & STi Sedans with OEM or OEM fitment (Nameless Performance) midpipe, not compatible with the STI (SPT) dealer installed midpipe.

Each axleback comes with a full hardware kit for installation.

Configuration Options:


  • Muffler Delete: The loudest option. Removes the mufflers entirely. This is a 10 on a scale where stock = 0
  • 4" Mufflers: Similar to the deletes, but with the edge taken off. This is a 7 on a scale where stock = 0
  • 5" Mufflers: Our most quiet option. Perfect for those looking for a subtle upgrade. This is a 5 on a scale where stock = 0


  • 3" Quad Staggered Double Wall: These are T304 stainless, double wall polished tips that fit perfectly into the cutout in the rear valence of the vehicle. 10 Degree Angle Cut with staggered arrangement (inboard tips stick out 1/2" further than outboard tips). 3″ diameter per tip, very close to an OEM look
  • 3" Neochrome Quad Staggered Double Wall: These blue flame/burnt tips fit perfectly into the cutout in the rear valence of the vehicle. 3" tip with a 10 Degree Angle Cut with staggered arrangement (inboard tips stick out 1/2″ further than outboard tips). These tips are only available with the Muffler Delete.
  • 3.5" Quad Staggered Single Wall: Single Wall Quad Tips in 3.5" diameter w/ 20 degree angle cut with a 1/2" staggered arrangement.
  • 3.5" Quad Non-Staggered Single Wall: Same as above but non-staggered.
  • 4" Quad Staggered Double Wall: Double wall 4" diameter quad tips, 1/2" staggered arrangement, 10 degree slash cut.

Installation Guide - Axleback/Catback/Midpipe

Recommended Add-Ons:

Urethane Exhaust Hanger Bushings

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 autocrossers or circuit racers.

    The 4" quad looks raw as fuck, an that growl sounds exactly how it should of sounded like out of the factory. With a full stock rest of the exhaust system, it still sounds raw. If your thinking about getting one, fuck it the stock system sounds gay.

  4. Amazing Workmanship

    I was surprised how quickly I received the product after I ordered. Once i received it, install was simple and quick and it gave me that sound i was looking for out of my WRX. Not overly loud, but perfect to get a little attention and some kick

    Decided to go with the 4in muffler and 4 in tips. Love the look and sound of my car. Always looking forward to cold starts. 4in mufflers are pretty loud and love the deep tone they bring.

  6. Quality

    I had to wait a little over a month for my 4 inch quad staggered axleback and I can definitely say it was worth the wait! Installation only took about 20-25 minutes. The qualty is awesome and the sound is amazing! After breaking it in, I do get some nice little pops and crackles. I 110% recommend this to anyone looking to add some solid sound for a great price!

    This should be standard coming from the STI factory, remove the restrictive and heavy mufflers Subaru. The pops and bangs that this exhaust makes with the 2.5T are quite impressive and provides a throaty rumble. The quality from Nameless Performance was great, welds and finish were outstanding. Great Job! My expectations were exceeded.

  8. Lovely growl

    Bought the 5" mufflers with the doublewalled 3.5" staggered tips.

    Cold cranks are definitely louder than I would prefer, but no one's complained yet. Pops and sputters when shifting always enhance the driving experience. Love the way she sounds now.
