 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)

Quad Staggered Single Wall 3.5":  Single Wall Quad Tips in 3.5" diameter w/ 20 degree angle cut with a 1/2" staggered arrangement.  (adds $30 to price)

Quad Non-Staggered Single Wall 3.5":  Same as above but non-staggered. 

Quad Staggered 4" Double Wall: Double wall 4" diameter quad tips, 1/2" staggered arrangement, 10 degree slash cut.  (adds $150 to price)

    BEST THING I HAVE DONE TO MY CAR YET! love the sound !
    I have the 5" mufflers and a mid pipe w/o mufflers or resonators.
    not terribly loud but, definitely louder than stock. Great boxer sound !
    Order it weeks before you need/want it!

  2. Exhaust is awesome! Shipping takes forever

    Posted by Diego on 27th Nov 2014

    This exhaust is awesome! One of the best things is that you can customize it to how you like it. The sound is amazing as well, nothing beats the pure sound of the Subaru rumble. In my state, Arizona, a muffler is needed on a car at all times so I decided to go with the 4" mufflers. Unfortunately, I found the law after buying the muffler deletes. This in no way Nameless' fault, I should have done research beforehand. The only reason why I'm giving this four stars is due to the fact that both my orders have taken more than a month to get to me. I realize that these are custom orders and that not everyone can ship in 2 days like Amazon, but I full month is too much time to get these awesome axel backs!

    Like some people have said on here, if you're thinking about buying these, don't think!! Just buy them! You'll be more than happy you did!!:

  3. A long wait. Well worth it.

    Posted by Kevin on 12th Nov 2014

    I'll start by saying that I waited 12 weeks for this product. It was annoying and customer service was never very helpful and extremely vague throughout the wait. However, after finally receiving the exhaust, I can easily say that I would wait 12+ weeks for it again if I had to.

    The build quality and welds are just fantastic. The fit/alignment of the exhaust on the car is just about perfect, and the tone is downright astonishing. I can honestly say that these muffler replacements sound as throaty and as loud on my STI as the COBB turboback exhaust sounded on my old WRX. It truly amazes me.

    It may seem pricey once you build out your ideal muffler setup. But at ~$650 these are still cheaper than any worthwhile catback and if the many dyno charts are to be believed, these free flowing mufflers can add just as much power as a typical cat back.

    I'm extremely satisfied.

  4. Excellent Product!!!!!!!!!!!

    Posted by Mike K on 29th Oct 2014

    Craftsmanship is great, and sound is outstanding!

  5. Quality stuff amazing results

    Posted by John on 26th Oct 2014

    The first thing I noticed was the build quality of this exhaust. The welds are beautiful, the pipes have to be at least 5-8 lbs less in weight than the stock mufflers. I have a 2014 STI, the installation took 30 mins total including removing the stock exhaust. I purchased 4 new exhaust bushing/hangars. With some silocone spray they are easily removed and installed. I was amazed that everthing lined up perfectly, i literally had to do no adjusting to get them even in the cutout. Maybe that was luck or maybe its amazing build quality. Once on something amazing happened when i turned the key. The notes that came out of the tailpipes tapped a part of my brain which simultaneously released every chemical in my brain and my mind exploded into a adrenaline unicorn rainbow keliedescope orgasm that is still occuring at this moment. Best $498 i have ever spent in my life.

  6. 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.

  7. 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

  8. 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.

  9. 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.

  10. 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.
