 Product Description

Designed for the VA Chassis (2015+) 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 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.
  • 3.5" Quad Staggered Double Wall: Double Wall 3.5" diameter quad tips, 1/2" staggered arrangement, straight cut, brushed finish.

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. just do it

    Posted by on

    bought these axel back along with the nameless cat back to replace my cobb exhaust. i was hesitant on buying this at first but then went ahead and did it anyways. it has a great tone , its loud when it needs to be, and quieter when you drive normal. i used to daily drive a straight piped vehicle for a while and the loudness of this exhaust satisfies my taste more than enough. get the muffler delets , you wont regret it! trust me on this one. best amount of money i spent on my wrx by far. thanks for an awsome product nameless. im extremly happy with this product.

  2. Satisfied

    Quiet on the highway and a great sound around town.

  3. Great sound, great price.

    I recently purchased the basic muffler delete axleback with 3" double wall. If you have the $ for the bigger tips, go for it. The 3" tips don't quite fill the cut outs in the bumper.

    The sound this system creates is much much better than stock. It is not too loud to be obnoxious. Cold starts are amazing and At low revs it has a nice low grumble. You have to get on the throttle to really make it loud. I have noticed a small uptick in gas mileage and power.

    Thank you, Nameless. I am proud to have a quality American made product that improved my Japanese car!

  4. Awesome fit sounds great

  5. Best exhaust for the sound!

    Bang for your buck sound and look! The 3.5in tips are perfect. For the car!

  6. I got 5 inch catback

    Everything was great! They have a perfect deep tone to them without being too loud in low rpms. Definitely adds some attitude to your WRX

  7. 4" axleback

    I live in an area where cops will pull you over for any little thing so I was a little nervous ordering this exhaust and thought I should've went with the 5" instead. Once installed I am extremely happy with my decision. The sound is perfect. Not too loud but gives it a nice deep grumble. At highway speeds there is absolutely no drone and it is almost indistinguishable from stock. It's a perfect exhaust for me because I can be quiet around town when I need to or can really light it up when I want to get on it. Fantastic and if you're at all concerned with cops do not worry, this is perfect.

  8. Still can't stop smiling!

    After purchasing and installing about 4 exhaust systems (from turbo-backs to axle-backs) I can confidently say that Nameless has delivered an OUTSTANDING product. The car is SILENT when idleing and truly roars and pops when you really step on it. The stainless is flawless and installation took me about 30 minutes. This is the perfect mod for anyone looking for a great product at a great price; all while keeping the new whip under warranty ;)

    I have had this installed for about a month now and have no complaints on the product (purchased an axle-back with 3.5 inch tips and 4inch resonators)
