Calculated at checkout

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.

Fits 2011-2014 STI and WRX Sedans.


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 sublte upgrade. This is a 5 on a scale where stock = 0

Tailpipe Tip Options:

Quad Staggered Double Wall 3" 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 Non-Staggered Double Wall 3" Tips: Same as the tips above, but even offset on the tips (no stagger)

  1. wow

    Posted by tattoofan on 10th Aug 2014

    Received my 4" axle back I am very pleased with the product construction and and fit were terrific, now as for the sound its great just what I was looking for my wife and kids also agree. I know that when I complete the rest of the exhaust it will get a little louder. I did have to wait 6 weeks but I am still pleased, Ryan was great at communicating with me and I do believe they are trying to get the wait times down and still make an amazing product.

  2. best bang for the buck

    Posted by Ryan on 3rd Aug 2014

    I read online people saying it's too loud, it is not at all. Perfectly acceptable at idle and good tone while revving. Awesome build quality fitment

  3. Excellent product

    Posted by Ravishing on 3rd Jul 2014

    Lots of good things to say about these.
    These really bring out the rumble of the engine and sound so badass at any rpm. The drone isn't too bad on the highway as if you like hearing your engine than these would be perfect for you. Definitely a night and day difference with the sound. I can't say it enough, these make my wrx sound like a bad mother f*****.

    They also look great. I have the 3.5 inch single wall which has a nice profile and sits even with the bumper. One thing I wish I would've know while purchasing originally. Buy some of the hangers nameless offers because the stock ones let the exhaust hang a little too low. Overall these things are well worth the money and should've been the first thing I bought. 10/10 no complaints.

  4. Awesome

    Posted by Unknown on 19th Jun 2014

    I got the axle back in about a week. It took me about 30 minutes to install and I have loved it ever since. Definitely not "too loud" or anything. Absolutely the perfect rumble and tone. I've taken it on road trips with no problem.

  5. Well worth the money

    Posted by Nate S on 12th Jun 2014

    I bought the muffler delete a few months back and it is awesome. I am just running the muffler deletes and it sounds nice and deep. It can be heard with the windows up and the radio up. I haven't noticed any bad droning in the cab. If you want a nice sound out of your almost stock wrx this is the way to go. It only took me 20 mins to do the swap.

  6. All you need

    Posted by G on 11th Jun 2014

    So nothing overly complicated or special about these. Some 2.25" bent stainless pipes with some nice quality tips welded on.

    Had the stock ones off and these on in about fifteen minutes. Everything lined up perfectly, look really good and sound great.

    I was concerned about running muffler less but quite honestly noise is not an issue at all. You get a nice burble and rumble at idle, and a nice roar when giving it some wellie. Had several people ask what they were at a recent AutoX event.

    Well worth the money.

    I find I'm running around in a lower gear more often because of the sound, throttle response and I actually find it louder in higher gear/lower rev.

    I just got done installing these on my 13 sedan and holy S@#$...i feel like im cheating on my wrx with an even sexier wrx! the sound in my opinion is night and day compared to stock. It's deep, throaty, and what the stock exhaust should have sounded like from the factory. Ordering was painless, shipping was fast and the product was well packaged. Like most people i read a ton of reviews, watched about 1000 youtube videos of different exhausts and talked to friends with subies before purchasing the muffler delete...my only complaint...i wish i would have ordered them a month ago! If you're in the same boat i was in...ORDER THESE TODAY, you won't be sorry.

  8. Nameless hit the nail on the head

    Posted by Jeremiah on 25th May 2014

    I only wanted a little growl around town and a scream at WOT but I wasn't expecting such a massive difference. At idle it isn't any louder than stock, casual driving it sounds a little throatier but no louder, but when you get on it holy $h!t does it make a noise. Its not that much louder than stock but it sounds like a demon. Just enough to get you excited but not enough to make your neighbors mad. Thanks again Nameless.

  9. unbelievable transformation

    Posted by Jr.. on 25th May 2014

    shipping was fast.. product was amazing, quality weld American made can not asked for more..i didn't even jack the car just went under and install them that's how crazy perfect the fit took me 20 mins.. if I jack the car 10 mins.. lol sounds great loud when you want and quiet when u want it to be quiet except cold start car is loud first 2 mins then it settles down .. thank you nameless you guys are the best.. p.s for those who are worried about cops with muffler delete set up? I have driven behind in front next to cops as long as you don't drive like a jack ass they don't even bother ... just always be carefull of your surroundings

  10. Awesome Sound

    Posted by Dan on 5th May 2014

    I just installed this exhaust yesterday and I am already loving it. It sounds so angry when it starts up and then tames down. Quiet when you want and loud when you get on it. The tips look perfect. In my opinion this is how the car should sound from factory. Money well spent.
