 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" 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" 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. Looks and sounds great!

    Posted by on

    Wanted a more aggressive sound without breaking the bank or turning the heads of police! This exhaust is right on the money. Insanely easy install, right in my car port, didn't use a lift or anything.

    Customer service is really easy to contact and answers questions with educated and finite answers.

    Highly, highly recommend.

  2. Great bang for your buck

    Posted by on

    Recently purchased this exhaust for my 2016 WRX . Wanted something a little more aggressive than the stock set up. Very pleased with the sound produced from this axle-back. On start-up, you'll turn a few heads, but it mellows out to a low growl on idle. Sensible driving is great, little to no drone which was what I was looking for seeing as a spend a good time of my day commuting. When power is applied, you can definitely hear it!
    Install was a breeze. Fortunately I had access to garage and lift, but a car jack and some stands would have been just as easy. Highly suggest getting the new bushings as well, as the stock ones are not the best.
    Overall craftsmanship of the product was topnotch, customer service was nothing but great, and the whole experience was painless.

  3. Unmatched quality and sound

    Posted by on

    Got the 4 inch muffler, quad staggered for my 2017 WRX. Couldn't be happier with it. Sounds amazing, loud on startup, quiet at idle and gets loud once you step on it. Only wish the tips came blue. But other than that, vey happy with the Nameless. Go with the 4 inch muffler. It's not that loud.

  4. Great product

    Posted by on

    Looks really nice and sounds great. Install took about 15 minutes. I am very happy with the purchase.

  5. These really should come stock on all Subarus.

    I don't often review stuff, but I'm very happy with this product. I got the 4in staggered double walls with the 4in mufflers, and it's perfect. Not too loud, not too quiet, and they really help fill out the look of the car. And at this price they're a great deal too. On top of that I got a military discount! Glad I went with Nameless.

  6. Sounds amazing.

    Posted by on

    I just installed my 4” muffler with 3” tips today and it sounds absolutely incredible. I was like everyone and couldn’t decide on muffler size but the 4” is exactly what I was looking for. Nice and deep sound at a perfect volume. Nameless customer support was also incredible and had my exhaust to me two days after ordering. Get this exhaust you won’t regret it.

  7. Excellent quality, Sounds good!

    Posted by on

    Quality is top notch, it sounds great, pretty loud on a cold start, calms down after about 30 seconds. Would definitely recommend this product. I’m bone stock with just this axle back, I think it sounds great.

  8. 4" tips with Muffler Delete

    Posted by on

    Amazing sounding axle back exhaust. This is how the car should sound from the factory. It's not that loud at all but it really allows that rumble to come through and it's got a quality sound exhaust note with barely any drone (at least with the muffler delete). Install is incredibly easy, maybe take you 45min tops. Aggressive sounding, quality welds and finish. If you are looking for something that is going to accentuate that exhaust note and bring that rumble out, get this axle back.
