 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" 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).

Installation Instructions:

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.

    Good affordable exhaust with a better tone than most I’ve seen around. Would recommend to any Subaru owner. Can not wait to install the rest of the system!

  4. axleback with 4" tips

    Posted by on

    Installed in less than 30 minutes. They fill in the bumper cutouts perfectly! Also had the axleback 3" tips before this and also have the midpipe. Love it.

  5. Love my muffler delete

    Posted by on

    Super easy to install and love the sound it gave my car. Deletes were put on my stock 2012 wrx sedan and it was exactly what I was looking for. Awesome product for the price especially.

    Unbelievable sound. Running the nameless muffler delete and a magnaflow midlpipe.. it sounds so means, best when it’s cold started and when you’re driving down the road at 2k RPM it’s unbelievably loud! Highly recommended and yes it crackles and pops too

  7. The crafsmanship of the exhaust and the welds were remarkable

    Easy installation, beautiful work. Worth the wait for the production.

    Love hearing it pop when it backfires

  8. Subie rumble loud & clear!

    Posted by on

    Finally I can really hear the Subie rumble from my 2014 STi sedan - thank you Nameless Performance!

    I installed my axle back muffler delete kit this past weekend and it sounds great. It’s much louder but I don’t think that it’s to the point will it will attract the police, especially if I keep the RPMs below 5000. At 3000 – 3500 RPMs on the freeway, it’s just a little louder than stock. The road noise from the tires seems to cover up a lot of the exhaust noise. That’s just from the driver’s seat though. I’m sure that my car is really loud from outside, especially from the rear. The great news is that there is no low frequency droning on the freeway, which is a big complaint that many stink eye owners have about their exhaust systems.

    At idle it sounds wonderful to my ears. It’s now a raspy growl and the Subie EJ257 rumble can really be heard now. Actually, the loudest sound is at a cold start up.

    The 3.5 inch brushed tips are just a little larger than stock but they stick out much further. I’d say that they stick out at least an inch further than the stock muffler tips did. I really like the straight cuts on the ends. I’ve never been a huge fan of slash cut exhaust tips on stink eye Subies. The exhaust really doesn’t look that much different from the stock one, which was exactly what I wanted. I don’t really want to attract any fix-it tickets. Unless someone is really familiar with what a stink eye Subie looks like from the rear, I don’t think that they’d be able to tell that I changed anything…as long as my engine isn’t running.

    Thank you Nameless Performance for offering several options for the exhaust tip size, finish, wall thickness, and cut angle. I chose the 3.5 inch/brushed/double wall/straight cut options. I’m very happy with how it looks.

    The install was very easy to do. It took about two or three hours and it would have been much less if I didn’t replace 100% all of the stock rubber exhaust hangers (five total) with polyurethane ones. Getting those new ones on was hard to do and today my fingers are still a little sore from the job. WD-40 helped to make it easier but I had to use a lot of it.

    If you want to unleash the Subie rumble from your EJ257, then look no further!
