 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:

  • 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.
  • 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.
  • Quad Non-Staggered 4" Double Wall: Same as above but non-staggered.
  • Quad Staggered 3.5" Double Wall: Double Wall 3.5" diameter quad tips, 1/2" staggered arrangement, straight cut, brushed finish.
  • Quad Non-Staggered 3.5" Double Wall: Same as above but non-staggered.

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. Awesome sounding

    Posted by on

    Definitely takes a while to get the product (about 5 weeks). Once it arrived however, the build quality was immediately evident. Protective packaging was meticulously done. Sounds great. The only issue I had was the right adjustment slots were not lined up PERFECTLY to allow it to sit perfectly in the exhaust opening. I just adjusted them slightly wider than stock. In all fairness, I did not contact NP regarding this, but would definitely recommend this product.

  2. Very good Product

    Easy to install, took about 20-30 minutes.

    Sounds mintttttt.

  3. Took Forever but mostly worth it.

    First off, if you decide this is the product that you absolutely must have, order it waaaaay before you need it. I ordered this and was told 3-4 weeks. Four weeks came and nothing, no email, no phone call, nothing. I called them and was told 2 more weeks. Again, two weeks came and nothing. Called again, 2 more weeks. Finally I got an update email saying my exhaust was in final fabrication. Then a day later got a shipping confirmation. They did upgrade my shipping to 2 day and gave me a free T-Shirt and license plate frame though.

    Now that that's out of the way, the product is absolutely awesome. Before I had the muffler delete which sounded really good but soon after I ordered a mid pipe and downpipe from them and then with the straight pipes the drone inside the car was too much. The guy did tell me when I ordered the mid and down pipes that it would be loud... I just didn't think too loud. I ordered the axle back with 5 inch mufflers and it's perfect. Mean growl when I get on it and just a little drone but much better than straight pipes. As always build quality is second to none. You can't go wrong with these guys.... when they aren't too busy. If you are on the fence about buying these, just sack up and do it. I promise you will be happy you did. Good job, Nameless, keep up the awesome work. Thank you.

  4. Amazing product!

    The build quality and craftsmanship of this product is phenomenal. Completely worth the wait. It came well packed and it shipped fairly quick. It's a beautiful exhaust and it completely changes the car, it sounds AMAZING. Super happy with this exhaust!

  5. Perfect sound

    I was nervous about the sound, I have a baby on the way. But after the inner kid in me went and bought the exhaust anyway I can honestly say the crisp, low-toned sound is not obnoxiously loud at all. I still smile ear to ear when I start her up.

  6. Worth the wait!!

    Good professional welds and craftsmanship. It sounded amazing with 4 inch mufflers axle back exhaust on my 2011 wrx. Customer service was an excellent experience. Contacted me via phone the next morning about my inquiry on status of my exhaust. Thank you all and keep up the good work!!!

    This product blew me away! i do not have a single bad thing to say about this axleback. The quality was great and it sounds amazing! I had a completely stock exhaust system on my 11 wrx and this axle back alone made the boxer engine sound awesome! So much deeper and throaty. It makes the stock exhaust sound pathetic haha. i Got 4 inch tips and 4 inch mufflers due to inspection laws where i live since you have to have a muffler and the sound couldn't be better. I had some friends over when i installed it and they said they have never heard an axle back sound that good and clean. Only thing i can say is order it before you want it! Took about a month an a half for me to get it from the time i ordered it since they do hand make it and its not just an exhaust sitting on the self and the wait was excruciating lol Most difficult part about the install was getting the old one off since my stock bolts were rusted to the y-pipe so i had to grind them off. Just make sure you order hardware with it because you never know when you need another bolt or nut. I can gladly say i will ONLY order nameless products for the rest of my exhaust system. They make fantastic products

    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!
