 Product Description

Designed for the VA Chassis (2015+) 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 restrictive baffled mufflers in lieu of a pair of mandrel bent, TIG welded, T304 stainless steel pipes and configurable tailpipe tip style, this system is easily configurable to your desired look and sound level.

Factory fit laser cut flanges and 2″ dual piping has equivalent flow characteristics of a 3" single straight pipe, providing excellent breathing characteristics for high end horsepower and generating an increase in low end torque (roughly 10hp/11ft lb at the wheels for this and the other muffled axleback options we offer).

Fits 2015 WRX & STi Sedans with OEM or OEM fitment (Nameless Performance) midpipe, not compatible with the STI (SPT) dealer installed midpipe.

Each axleback comes with a full hardware kit for installation.

Configuration Options:

Mufflers:

  • 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

Tips:

  • 3" Quad Staggered Double Wall: 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, very close to an OEM look
  • 3" Neochrome Quad Staggered Double Wall: These blue flame/burnt tips fit perfectly into the cutout in the rear valence of the vehicle. 3" tip with a 10 Degree Angle Cut with staggered arrangement (inboard tips stick out 1/2″ further than outboard tips). These tips are only available with the Muffler Delete.
  • 3.5" Quad Staggered Single Wall: Single Wall Quad Tips in 3.5" diameter w/ 20 degree angle cut with a 1/2" staggered arrangement.
  • 3.5" Quad Non-Staggered Single Wall: Same as above but non-staggered.
  • 4" Quad Staggered Double Wall: Double wall 4" diameter quad tips, 1/2" staggered arrangement, 10 degree slash cut.
  • 3.5" Quad Staggered Double Wall: Double Wall 3.5" diameter quad tips, 1/2" staggered arrangement, straight cut, brushed finish.

Installation Guide - Axleback/Catback/Midpipe

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. Excellent

    Posted by on

    The product so far seems to be functions great, not obnoxiously loud but sufficient increase in aggressiveness. My only complaint is that it took over a month to receive. I knew it had along lead time however it was the only downside.


  2. It took me a week or so but, I now love them!

    Posted by on

    These are high quality with a great finish. I am a welder and craftsman myself and have to say, I am very impressed with the welds and finish of the pipes and tips. I got the muffler delete with the 3.5-inch double wall tips. When I first installed them I believed them to be loud and possibly obnoxious. I almost immediately removed them. I decided to give them some time. As some folks have stated, they did seem to mellow with time. I don't know why that is since there are no mufflers. I would cold start my 2017 STI and stand behind it and the sound began to grow on me. When my car warms up, the sound is amazing. The rumble is not harsh nor is it shrill. The pitch is very well balanced. I then had a friend get in the car and modulate the throttle and rev the engine. It is really not all that loud but, it is noticeable. Backing off the throttle from higher RPMs provides a pleasant series of pops and rumbles. Quick shifting will get your heart pumping. The sound is very similar to an old Porsche racer.

    After about a week of discerning whether or not I wanted to keep these pipes, I decided that I would and I am happy I did. I look forward to driving my STI more than ever. These may not be for everyone but for me, they are fantastic.

    In closing, I want to state that I am a 55 year-old and have always been a "car nut". In no way do I want to draw attention to myself but, I love these pipes! I highly recommend this modification.


  3. Good exhaust

    Posted by on

    Give a very deep note with every cold starts and above 3 k revs, quiet on the freeway( no drone) but can still hear the exhaust note when accelerating


  4. Amazing

    Posted by on

    I read probably close to 100+ reviews before purchasing. This product is everything and more than I expected. It was a huge change from the stock exhaust but once I was used to it and figured out how to expose it or hide it, it's perfect. I couldn't stand that I couldn't hear my car! This delete helped me overcome that problem. The craftsmanship is second to none. Highly recommend!


  5. Exactly What I was Hoping For

    Posted by on

    I looked around a lot for exhaust systems from turbo-backs to axle-backs. I settled for these and couldn't be happier! Installation was easy, took me about an hour by myself from getting the car off the ground through final adjustments. I got the 4" Tips w/ 5" mufflers and got exactly what I was looking for. It's pretty quiet until you give it some gas. No droning what so ever and the 4" tips fill the pockets perfectly. There's no need for a tune if you don't want to which is also a plus for me. I probably could have gotten the 4" mufflers but I still have no regrets. If you want better sound and a little bit better air flow get these axle backs you won't be sorry!


  6. axle back exhaust

    Posted by on

    This thing is awesome, Good price beautiful welds and fitment. Sounds beautiful


  7. Great product.

    Posted by on

    This part is well done. The welds are near perfect all the way around. This axleback exhaust system is perfect , not too loud, not too quiet.
    The only complain I have is about the gap between the read bumper cover and the exhaust tips.


  8. WORTH EVERY PENNY!!!

    Posted by on

    This is the best purchase I've made for my 17' WRX!
    Highly suggested to everyone ! I've already got on of my buddies to but this because he fell in love with everything about them!
    I got the 4' tips with deletes and it's such an amazing sound! I love the crackles and pops! And there is no drone on a great sound while in 6! Best sound for such a great price !
