 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 Instructions:

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. Great product.

    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.


  2. WORTH EVERY PENNY!!!

    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 !


  3. High Quality, Great Sound

    I thought I loved driving my 2017 WRX when I first got it. Now I have put the Nameless 5" axle back mufflers with 3.5" tips, and I love it even more. Adds that great Subaru rumble without being excessively loud. Not to mention the quality is outstanding and was very easy to install yourself. I give it an A+.


  4. Unbeatable!!!

    The axelback muffler deletes were extremely easy to install. Me with the help of one other person completed the project in about 45 minutes. First start I knew I made a good purchase. It sounds great but it nothing too overbearing. I really love the pops and gurgles when down shifting...probably may favorite part. Construction of this product was incredible. I would be lying if I said I wasn't going to finish with a mid pipe to make it catback. Nice work Nameless!


  5. Very nice construction

    I'm very happy with this first purchase. I plan to try some of your other parts!


  6. Best purchase I could have made

    Posted by on

    I bought the 4" muffler w/ 4" tips for my 2017 STI and I couldn't be happier! I went with a muffler set up because I didn't want it to be obnoxiously loud but still wanted that authentic "subie" rumble. These were more than perfect, louder than I originally thought they would be but gives off that deep note that I have been wanting. The tips look great and fill the gap in the rear. If you have an EJ engine and want a smooth boxer rumble you won't go wrong with this set up. Thank you nameless for the quick making and shipping of this item. 10/10


  7. Awesome product

    The sound is amazing. It completely exceeded my expectations. The 4" resonator is a perfect volume for me. The craftsmanship is perfect. You can tell it's made to last. Couldn't be happier with the product. Only reason for 4 stars is a longer wait time than I was told when contacting the shop. Completely worth the wait.


  8. Awesome
