 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. This will NOT fit the 2019 STI or the 2018 STi R/A. 

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" Double Wall: These are T304 stainless, staggered 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
  • 3.5" Single Wall: Staggered ingle Wall Quad Tips in 3.5" diameter w/ 20 degree angle cut with a 1/2" staggered arrangement.
  • 3.5" Neochrome Single Wall: Same as above but with blue flame/burnt tips fit perfectly into the cutout in the rear valence of the vehicle. 3.5" tip with a 10 Degree Angle Cut with staggered arrangement (inboard tips stick out 1/2″ further than outboard tips).
  • 3.5" Double Wall: Staggered Double Wall 3.5" diameter quad tips, 1/2" staggered arrangement, straight cut, brushed finish.
  • 4" Single Wall: Staggered single wall 4" diameter quad tips, 1/2" staggered arrangement, 10 degree slash cut.
  • 4" Double Wall: Staggered double wall 4" diameter quad tips, 1/2" staggered arrangement, 10 degree slash cut.

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. its awesome

  2. Rumble Rumble

    Ordered mine on a Tuesday. It was delivered the following Tuesday. I had my concerns when I saw some people waited a month or more to receive theirs. But it was delivered super quick. Install took about 45 mins with basic tools. Definitely watch a video or two on installs and you will be good. Sounds great. I went with the 3.5 tips and they look great as well. Highly recommended mod that is pretty affordable. There are cheaper options, but if you are worried about saving $100 on such a cheap mod, your going down the wrong rabbit hole.

  3. Best looking/sounding exhaust I have ever had!!

    Posted by on

    Bought a axleback exhaust for my 2016 WRX with 4in tips and muffler delete. Man it took almost a month to get it but when I saw the craftsmanship and quality put into it I didnt mind the wait at all. The welds are awesome and look like amazing hand welds. The sound is perfect(no drone, loud when you get on it, and pops like crazy)! I couldn't have ask for anything more perfect. I will be buying more parts from nameless in the near future.

  4. Music to my ears !

    By far the best axleback on the market . I am completely happy with this product. So much better than stock. I'm running the 3" double wall muffler delete. Highly Recommend.

  5. 5” Mufflers

    Posted by on

    So I was running catless j pipe with straight exhaust. Sounds “cool” for a little but really starts annoying your ears from loudness and drone. The nameless 5”mufflers are perfect! Great sound at idle and mid range and still screams at higher rpms without the drone. Great shipping speed and packaging from the company as well.

  6. The Perfect Rumble

    Posted by on

    The muffler delete cat back is by far the nicest and best sounding exhaust I’ve heard. I think it has the perfect tone without making you or your neighbors def. It crackles in low rpms and screams at higher rpms. 10/10!

  7. Fabulous quality & sound!

    Posted by on

    Installed the 4" muffler axleback on my 2018 WRX, the quality of product was great, and sounds great, it has a nice grumble to it with a little popping on downshift, NO DRONE, not to loud but louder than stock.

  8. Best muffler for the WRX

    Posted by on

    The 4 inch tips and 4 inch mufflers is the way to go. In my opinion it's the best sounding exhaust for wrx's. I've heard muffler deletes, and they're way too raspy. The exhaust note is on par with any other Honda cars. The 4 inch nameless mufflers gives the wrx a deeper tone that sounds just right.
