 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. 3" muffler delete

    Posted by on

    The muffler delete arrived super fast especially all the way to New Zealand. Super easy to install bolts right up and fits perfectly into stock hangers and most of all sounds amazing! Will definetly reccomend!

  2. 3.5 muffler delete

    Posted by on

    Sounds amazing! Deep rumble but not over bearing when crusing. Shipping did take a while but worth the wait.

  3. 5" muffs and 3" tips on 2011 wrx sedan

    Posted by on

    Paired with a cobb dp this sounds great. Even with the 5" muffs its still a good bit louder than stock. I didnt want to be heard from 3 blocks away so this is good for a more subtle application

  4. Good product

    Great sound!!

  5. Exactly like all the other reviews

    Not much to say.
    One of the best purchases (next to sway bars) that I've ever made for the car. It is the absolute perfect volume. Loud when I step on it and no drone on the highway.
    Love it.
    The waiting part is probably my least favorite. Customer support was fine but I got different answers from different people.
    Got to give them credit, going through hundreds of orders with only a few guys.
    Absolutely awesome.

  6. 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.

  7. Very good Product

    Easy to install, took about 20-30 minutes.

    Sounds mintttttt.

  8. 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.
