Calculated at checkout

Product Description

Designed for the 2011 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 and configurable tailpipe tip style and positioning (fwd to aft for distance to the rear valence).

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

Fits 2011 STi and WRX Sedans.


Tailpipe Tip Options:

Quad Staggered Double Wall Round 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.

Quad Straight Double Wall Round Tips: Same as the staggered, but even offset on the tips (no stagger). 3″ diameter per tip.

Quad Single Wall Slash Cut: Single Wall Quad Tips w/ 20 degree angle cut.  3.5″ diameter per tip. These can be staggered by ½” to match the valence better for an extra $30, please call to place your order.

Coating Options:
Bare:  Just bare, TIG welded T304 Stainless Steel. +$0/pair

10% Gloss Black Powdercoating (masked polished tips):  This high temp powdercoating is made for exhaust sytems and is an industrial finish.  Parts are prepped through multi step blasting, etching and cleaning process prior to powdercoat for a rust free substrate layer and durable finish.  Color is almost flat black, but has just enough gloss in it for ease of cleaning.  +$85/pair

    The Axleback with the 4 inch tips have made a massive difference in the sound and look of my car! Looks great! Purchase this now if you're on the fence about it!

    great product and a bang for the buck

  3. Simply Amazing!

    Posted by Mathew Smith on 3rd Apr 2014

    I am very impressed with nameless. I ordered my 3.5in muffler delete kit on Monday and received them Wednesday. Although, I did pay $70 for priority shipping. I bought these instead of a more popular system simply because of the price factor and great reviews. For the money, this system is fantastic. It is now the best sounding car I have ever owned! And this is coming from a guy that has had two modded V8 muscle cars before my WRX. I love it, the sound is polished and very smooth. And it is loud, but not too loud in my opinion. It is perfect!

  4. Best on the market!

    Posted by Mario on 26th Mar 2014

    Always wanted the extra Boxer sound from the WRX & yes NAMELESS delivered what I believe the best muffler delete on the market.
    Quality, Install, Fitment & Sound is 100% Pricing for the product is great too.
    For all those International buyers, as I’m situated in Australia  Have no fear, Packaging of the product was spot-on making sure it wouldn’t get damaged on the way.

  5. HOLY #$%^

  6. Absolutely amazing!

    Posted by Austin on 1st Mar 2014

    The sound difference these muffler deletes made is nothing short of spectacular! Best sounding exhaust I have heard, and I cannot wait to get myself the downpipe and midpipe to go with it! Not to mention the 3.5" tips look soooo much better than the tiny stock tips. I wish that Nameless offered an unequal length header to go with it, I would buy it in a heartbeat!

    So when I installed this I thought it was pretty loud, my hearing is a bit messed up so it is hard to gauge exactly how loud this is. My wife says when I go pick her up that she could hear my rumbling a block away. I just recently installed SF intake from cobb with APv3 and exhaust rumbles over the wooosh sound mostly at WOT. They both mixed very well though, at high enough boost the woosh is loud enough to turn heads and make them crap their pants with the rumble.

  9. A must have upgrade !

    Posted by Rahul on 15th Jan 2014

    Great price and excellent build quality. The 3.5 single wall axle back on my 2011 wrx totally changed the look and sound. Much more aggressive sound but not to loud. I got the flush tip placement so it fills up the space between the diffuser and bumper the stock tips left empty. I Would definitely buy nameless parts again!

  10. Makes me smile ear to ear!

    Posted by Chris on 9th Nov 2013

    I got the 4inch tips staggered flush with valence for my 13 WRX Sedan, and they are B-E-Autiful. On and off the car haha. And as many videos as I watched/listened to, none of them did justice to how amazing these sound. These deletes combined with a catless DP are my perfect idea of the boxer rumble, just with extra volume ;D
