 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. JUST DO IT!!

    Posted by on

    Hands down the best sound you can achieve on a budget.
    Very easy to install all hardware included. Made my wrx sound
    Like a whole new car. Super great quality and welds.
    Highly recommend. Muffler delete and 3.5 tips are the way to go

  2. 5" Mufflers w/ 3.5" Non-staggered Single Wall Tips

    Posted by on

    Let me preface this review by saying I don't vape, wear white Oakleys, have any flat brimmed Monster hats, or have any "Hoonigan" stickers on my car. That being said, I knew the muffler delete wasn't going to be for me.

    I initially ordered the 4" mufflers w/ 3.5" non-staggered single wall tips but was contacted by Steven from CS who told me the build dates on those were way out. Instead, he told me they had the 5" muffled version w/ the same tips ready to ship same day. I was hesitant because I wanted to make sure my WRX rumbled a bit but Steven insisted the 5" mufflers would be perfect. I told him to go ahead and switch my order.

    Fast forward two days later and it arrived! The build quality is superb. Install was very easy and straight forward. The sound is absolutely perfect. Quiet idle and when cruising, very rumbly when accelerating. Virtually no drone. It's a lot of money considering there are no performance gains but it puts new life in the car and looks better from behind, too. 5/5 would buy again.

  3. Easy install and sounds great!

    Posted by on

    Took 30 minutes to install back bushings and axelback. Sounds great too! Only thing is seems hanger on left side was a little off. Left side is about 1/2 inch lower and will need to try to adjust even though they sit exactly the same on bushings. Other than that I highly recommend this product.

  4. Clean, easy and simple

    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!

  5. Perfect Sound!

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

  6. 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.

  7. 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.

  8. 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.
