 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:


  • 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


  • 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.

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. Beautiful product

    Posted by on

    Looks and smells great lol. looks like real top quality work. a breeze to install. sounds so damn amazing, i just wanna keep driving. who needs a stereo.

  2. As I expected after reading all the great reviews !

    Posted by on

    Bought the 4 " double wall tips with 4" resonators for my wife's brand new 17 WRX.. As others have said, 4" tips fill out the gap, I would not get any smaller since once you remove the stock exhaust, you will need to fill the gap otherwise it looks odd seeing the empty space where the large stock muffler was, the 4" tips are perfect. Lots of room (3/4 of an inch) on either side of the tips so they don't hit or risk melting anything. Took us aprox. 1 hour from start to finish. Sprayed lube on hangers/bushing for removal of stock exhaust as well as install of new ones so they slipped on/off with ease. We installed new Nameless bushings near the tips.Research showed to tighten nuts to 35.4 foot pounds. I rounded it up to 36 foot pounds. I did back the car up onto blocks of 2"x6" wood pieces at rear which gave me a little more room to work as it's pretty tight without it being on ramps etc. but definitely doable. Be sure to remove the round metal factory gaskets and install the new oval type included from Nameless. Wife says she loves the new sound, hasn't had radio on since install lol She wanted the car to sound like it has 268 HP ....now it does.Deletes may be too much sound for a 30 something professional but 4 " sound awesome. Cruising on highway quiet but turns heads when on the gas. Was over a $1000 by the time Canadian exchange and delivery but is the sound difference enough to warrant the cost...most definitely !

  3. Canadian WRX eh?

    Posted by on

    Great product, ordering process was painless, came in about a week to Toronto, Canada. Loved the quality out of the box, got the dual walled, 4 inch muffler delete.

    Fell in love from the first start up!

    Also made a drive video on my way to work, shows the interior volume quite well.

  4. Im in love!!

    First I want to say service for my order was great and very helpful. This purchase exceeded expectations. I felt like a little kid as soon as I started up after install. The 4" muffler delete is loud, but not too loud. 5/5 would recommend.

  5. Purrfect tone

    Posted by on

    I live in a quiet neighbourhood, and under much review decided on the "4" inch mufflers & 4 inch double tips. When starting up in the garage in morning, I would say just about twice as loud as original mufflers, but this I expected. Then after 1-2 min warm up I'm leaving, it cuts down to close to original decibel level. This way I keep in first gear, up my street and out of my sub division. OK my review, the tone, for me and others
    who commented is perfect. I think its a toss up, if you go with 4 or 5 in mufflers, its all about the tone. I:ve heard the 5 in on you tube, {same car} sounded great too. Another thing, I will mention, is the 4 in tips, to me, they were the perfect choice. They are not some cheap clamp on tips they are nicely formed and fill out exhaust cut outs on my 17- WRX perfectly. The installation, is not a problem, because the specs are spot on and everything lined up perfectly straight. Thank You Nameless Team.

  6. Great! It honestly thought it was louder

    Posted by on

    Great product. Easy to put on. Didn't come with a koozy. Not much louder than stock when warmed up, but screams at WOT! 4/5 because of my inner child that wants more sounds (compared to my pypes pipe bombs on my 4.6 GT) but love it as a mature professional adult. Thank you and keep up the good work!

  7. As advertised!

    Posted by on

    Great quality exhaust, exactly as advertised. I went with the 4" muffler option with the axleback on my '17 WRX and it adds a great sounds but is not abnoxious loud. Love it!

  8. Perfectly loud

    Posted by on

    Easy installation and perfect sound quality worth every penny
