 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.

  1. 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!

  2. This shit sounds great

    I Got the 3.5 double wall staggered muffler deleted or much 14 wrx and it sounds killer!! Install literally took 20 mins great sound for the price waiting for it to get there sucks tho took forever

  3. Fantastic Quality

    Posted by on

    Ordered my Muffler Delete Axle Back for my 2011 STI and am very impressed with the quality of the product. Great looking axle back, and the sound is next to none. I have ordered a midsection to complete my catback. Can't wait for that to come in. Loving the Nameless products!

  4. Unsure at first..incredibly happy!

    Posted by on

    Felt like I need to write a review because I was on the edge with ordering this for literally a month. Lemme first say I was definitely unsure with this exhaust considering how cheap it was. Didn't wanna make my 14 wrx sound like a 1998 civic with one of those fart can exhausts (what I call 'tinny' sounding). Installation was a breeze, took me 5 minutes to take off the older exhausts. Wd40 and a 14mm wrench took them off with ease. New exhausts went on easily. I got the 3.5" non staggered muffler delete single wall. Looks fantastic, fills out the well way better than stock. The exhaust sounds incredible. I thought the muffler delete might be a little too loud for me but it sounds so so so much Better. Deep boxer rumble at idle and quite unless you start to get in it. Popping galore! Music to my ears, this is how the wrx should sound stock from the factory. Well done Nameless, welds and quality were A+. Muffler delete is the way to go hands down!

  5. 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

  6. 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.

  7. 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.

  8. 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!
