 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:

Mufflers:

  • 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

Tips:

  • 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.
  • 3.5" Quad Staggered Double Wall: Double Wall 3.5" diameter quad tips, 1/2" staggered arrangement, straight cut, brushed finish.

Installation Instructions:

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.

  1. Spectacular Carftsmanship

    Posted by on

    Went with a 4" muffler & 3.5" double walled tips. Sounds great. Not obnoxious. Just enough rumble to wake up the neighbors in the mornings. Comes alive on throttle....no popping.


  2. Just received my axle back

    Posted by on

    I love the fact that these guys are a small operation and take the time to put quality and personalization in every single product. Even though my product was built per order, I received it within a week from ordering it. Incredibly easy to install, didn’t even need to jack it up. Has awesome ‘mean’ sound with the 4” muffler on my ‘17 WRX. Couldn’t be happier with my decision to go with Nameless Performance.


  3. Axle back , muffler delete

    Posted by on

    Love it. I needed a little noise to shift. Great. Don’t need to look at rpm to shift. Got the 3.5 inch outlets. Look great.


  4. Completely Satisfied

    The 4" mufflers are just right. Suits the character of the WRX. Quiet during warm start and idle with none of the stock muffler drone. Thrilling tone at heavy throttle. 4" Tips with 4" mufflers look and sound great. Good fit and finish. 10-15 lbs lighter than stock. I'm happy.


  5. 4inch muffler delete

    Posted by on

    If you want a tuned sound coming from a stock car the deletes are perfect! Pops and crackles on downshifts but also makes explosive gunfire noises on quick accelerations.. it will surprise people


  6. axelback 4in. mufflers with 3.5in. double wall tips.

    Posted by on

    bought my 16 sti brand new. always knew I wanted to upgrade the exhaust. waited a while and was up in the air about it. didn't want to seem like a 19yr. old racer with a fart can for an exhaust. after listening to countless videos I was between the muffler deletes and the 4inch mufflers. called nameless and Tyler broke down the exhaust profiles . so glad I went with the 4inch mufflers. at 36 loud is good, but too loud is no good. deep rumble to say the least. and the tips fill the rear defuser perfectly. couldn't be happier. thanks nameless! 6 stars is more appropriate


  7. Clean

    Sounds so good in a word phenomenal


  8. Excellent quality w/ no wait!

    Posted by on

    It took a long time for me to decide on an axleback. I kept going back and forth between the 4" and the muffler delete. I ended up going with the 4" muffler with 4" double wall tips. They sound amazing! It's expensive but the quality is excellent. It also arrived at my door a week after purchase!
