 Product Description

Designed for the 2011-2014 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 mufflers in lieu of a pair of mandrel bent, TIG welded, T304 stainless steel pipes.

Factory fit laser cut flanges and 2″ dual piping has equivalent cross sectional area of a 2.85″ straight pipe or mufflers, providing excellent breathing characteristics for high end horsepower as well as retaining low end torque.


Muffler 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

Tailpipe Tip Options:

  • 3" Quad Staggered Double Wall Tips:  We think these are the best option, 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.
  • 3.5" Quad Non-Staggered Single Wall: Single Wall Quad Tips in 3.5" diameter w/ 20 degree angle cut with a non-staggered arrangement. 
  • 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. Clean, easy and simple

    Posted by on

    An amazing and quality products delivered by some similar type people!

    I personally got the 4inch double wall tips with the muffler deletes, the look, the sound and Subaru rumble deliver exactly what nameless was describing in their products.

    The sound isn't as loud as you would think, just at cold starts it gets loud just because... well cold starts... but after warming up the sound isn't overly obnoxious at all, more of a gentle aggressiveness with every push of the throttle.

    Thank you nameless for a quailty product that i am proud to own!

  2. Perfect Sound!

    Definitely worth buying. Perfect Subaru burble some extra whammy. Just buy it, you won't be disappointed!

  3. Axle-back muffler delete

    Posted by on

    Awesome part!! Right out of the box you can tell that Nameless takes their time to deliver quality products. It was a breeze to bolt on did it, in about an hour. Once it was on, the 4" double walled tips look absolutely amazing. Now once you turn the key, you can definitely hear the difference. Nameless nailed a unique tone that makes driving much more enjoyable. Thank you Nameless for a great product.

  4. Good quality sound not too loud

    Posted by on

    When ordering this product we were worried it would be too loud since it has no mufflers. We were very pleased with the volume and pitch of this exhaust.

  5. Best mod yet!!!!!!!

    Posted by on

    i just got a 2013 WRX a month ago, and like everyone else thinks the stock exhaust sucks. after i purchased the 3.5" muffler delete. and installed it, the first start is orgasmic. i seriously screamed in excitement, it looks and sounds sooooo badass. BE AWARE the muffler delete is A LOT louder in person then the videos. but the good thing is you can kind of control the loudness. at cruise you cannot even tell, but as soon as you step down it is super loud. not honda civic sound, the deep deep subaru loud. words can't even describe. just buy it, you will NOT be disappointed. not to mention my car is 100% stock.

  6. 14 WRX Exhaust

    Posted by on

    I have a 14 WRX and put on the 3.5 staggered double wall axle back system. Price was a huge consideration and Nameless is about half the price of the others out there. IMO, the Nameless exhaust is perfect. I was looking for a low key Subie "burble" - something I would enjoy and nothing that would announce I was coming like some of the loud "coffee can" pipes out there. It has a great sound to it and its easy to carry on a normal conversation with the windows up or down. If the stock pipes were a 0 on a scale of 1-10, I would put these at a 5. Just a sweet mellow Subie tone.

  7. 3" muffler delete for 2013 wrx

    Posted by on

    Firstly the service was fantastic, Jason really kept me up to date with when it was shipped etc! I ordered from Perth, Australia and it took 10 working days to come (spent a week in aus, less then in America to aus). Packaging was first class and the make of the exhaust is top quality! I have done any other mods to my car so this was put on a stock system. I wanted a bit more of a grunt out of my baby and this axle back has delivered the goods! Couldn't be happier!!!! Install took dad and I about an hour

  8. Stock and with a turbo back.

    Posted by on

    First off, I didn't actually buy these, but I bought the car with them already on. 3 1/2" muffler deletes. Probably the real reason I bought the car. I wasn't really in the market to buy a $20,000 car. But when I went to the dealership and started it, it was over. Just with a stock exhaust these sounded incredible. Perfect really. No drone, not ear bleeding loud, not too much attention if you know what I mean, but just simply perfect. After having the car about 6 months I finally paired it all up with the catted DP and mid-pipe. Much louder, a little drone, but wicked sounding. I love sick sounding cars, and it made mine that sick sounding car. I haven't heard too many others like it. Everyone always asks what brand. I always tell them Nameless. Always confuses them. But they never forget after hearing it. I will literally stand outside the back of my car after starting it up just to listen to it. the fitment, and overall quality with both the nameless mid-pipe and stock are perfect. Getting the mid-pipe and axlebacks too lineup were a bit of a pain (you have to twist the mid-pipe until it lines up, the manufacturing is perfect), but totally worth it.
