 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. Very nice construction

    Posted by on

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


  2. 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


  3. 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.


  4. Awesome

  5. Phenomenal Sound and Craftsmanship

    Posted by on

    The first thing I noticed out of the box was the quality of the materials and welding. Install was simple on my 2017 STI. I was able to remove the bolts without lifting my vehicle(results may vary). One of the exhaust hangers was a bit difficult to reach on the stock exhaust this way, but I managed. Once on the sound was above expectations. It's deep and not overly raspy. Downshifting above 3K RPM rewards you with a symphony of crackles and pops.

    CONS: This is a muffler delete... Yes, it's loud. It's not full out straight pipe loud, but enough to get a lot of attention if you have a lead foot. If the law enforcement in your area are sensitive to modified/loud cars maybe consider the 4" or 5" mufflers.

    If you shift at ~ 2K RPM each gear it stays mostly in line as for neighborhoods and when near police. Still grunty enough to set off the extra sensitive types though.


  6. Great build quality!

    I have ordered the four inch muffler delete for my 2016 Subaru STI sound is amazing real deep rumble, not as loud as you think it would be. The pops are nice, as well as the cold start. Feels as the car is less restricted. Four inch does do a great job in filling up the gap, and looks mean!


  7. Awesome Exhaust and Great Quality!

    Posted by on

    The whole ordering process was excellent from begining to end! The exhaust arrived packaged perfectly and the quality is top notch, welds are amazing! Installed with the 4 suggested Nameless hangers and the fitment was spot on! The exhaust tone is nothing short of wicked! I got the muffler delete 4" tip double walled setup for my 2017 STi and am super stoked! I hardly listen to the radio now just roll with the windows down and the exhaust note is all you need... music to the ears! Keep up the great work guys! A++++++


  8. Well done Nameless!

    Posted by on

    I ordered the 4" axleback with 4" tips for my 2018 WRX. The exhaust itself is great and you can see the attention to detail. Installation was easy and the fit is near perfect. The 4" tips fill the exhaust cut out nicely. Delivery took less than 1 week.

    The sound is amazing and under no circumstances would I say this is too loud. If your comparing the 4" and 5" I hope this helps. The sound is only as aggressive as you make it and cold starts are fine.
