 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.

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. Wow I am very surprised by how good these muffler deletes sound

    Posted by on

    I bought these for my 2018 WRX and with the elh I wasn't expecting a deep rumble like the ulh. Well they are deep and they roar. They are honestly tame when you drive normal but once you punch it they are LOUD. I got the 3.5 neo chrome tips and they look good and fill the bumper great. They also pop quite a bit too.

  2. 4in muffler delete

    Posted by on

    All I can say is wow. The customer service is top notch and I couldnt be happier with my purchase. Took me a total of 20 mins to install the axelback in my garage. Get the muffler delete. I am 26 years old with a 2 year old. I wanted something with character but wasn't overbearing. After watching countless youtube videos I bit the bullet on the muffler delete and lets just say I would have been upset at myself If I went with the muffler versions. It is the perfect level sound with very little (I mean LITTLE) drone.

  3. Axleback muffler delete

    Posted by on

    I already had the nameless catback but with mufflers on the axleback. I wanted a more aggressive sound and this did it. Hands down best exhaust setup.

  4. The Exhasut That Changed Everything

    Posted by on

    The day that this box came into my mail, I knew my life would be changed forever. Out of the box, I had a nice note about warranty and about certain other manufacturing things. Everything was clear and concise and my beautiful metal sound cannons were pristinely packed. After the short install I was ready for my first startup. Upon turning the key, my life was changed forever. It was late because of my work schedule, but that didn't stop me from redlining around the neighborhood. My friend who was riding passenger was afraid I was going to hyperventilate from the dumb smile I had on my face, I really was speechless. All in all, over the last month of ownership I can say that it really does live up to it's name as one of the best on the market, and the price point, you CANNOT beat.

    TLDR; I bought this and I love it, you won't find anything better for the price point and I would highly recommend this to anyone looking for an aftermarket exhaust that's easy to install.

  5. You get what you pay for

    I have no problems with this axle back I like how there's so many different styles and options to choose from...arrived in a very well packaged box and well wrapped tips...

  6. 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.

  7. 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.

  8. 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.
