 Product Description

Designed for the VA Chassis (2015-2018) 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 2015-2018 WRX & STi Sedans with OEM or OEM fitment (Nameless Performance) midpipe, not compatible with the STI (SPT) dealer installed midpipe. This will NOT fit the 2019 STI or the 2018 STi R/A. 

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" Double Wall: These are T304 stainless, staggered 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
  • 3.5" Single Wall: Staggered ingle Wall Quad Tips in 3.5" diameter w/ 20 degree angle cut with a 1/2" staggered arrangement.
  • 3.5" Neochrome Single Wall: Same as above but with blue flame/burnt tips fit perfectly into the cutout in the rear valence of the vehicle. 3.5" tip with a 10 Degree Angle Cut with staggered arrangement (inboard tips stick out 1/2″ further than outboard tips).
  • 3.5" Double Wall: Staggered Double Wall 3.5" diameter quad tips, 1/2" staggered arrangement, straight cut, brushed finish.
  • 4" Single Wall: Staggered single wall 4" diameter quad tips, 1/2" staggered arrangement, 10 degree slash cut.
  • 4" Double Wall: Staggered double wall 4" diameter quad tips, 1/2" staggered arrangement, 10 degree slash cut.

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. 4in Tips 5in Muffler

    Posted by on

    Awesome product! I've had it on the car for over 5,000 miles now so I figured I'd give my 2 cents. I'll buller point so it's easier to follow and easier for me to type (lol)

    Really awesome craftsmanship with the welds all the way around. Fit like a glove and had no issues with installation. Literally took maybe 25 mins to take off old mufflers and throw these new ones on. Didn't have to lift the car up on jacks or anything. (Buy the additional rubber hangers, you'll want them!)

    4 inch tips are perfect size for the car. The 3's are about stock size and me personally, I think they're too small. 4's really fill the back and make the car look a lot more aggressive. I went with double wall as well. Mufflers don't take too much away as far as sound and actually look good when sitting on the back of the car. Fills in more of the empty space you would have if you don't go with the mufflers.

    If you're shopping for a muffler delete, you're probably thinking one thing; be loud. I wanted to achieve a new tone to the exhaust but yet didn't want anything overbearing. Or just plain old Ricey. So that's why I got the mufflers on there. Best decision ever. I hate hearing other WRX's with just the cheapest option muffler delete and it sounds/looks like trash. Muffler definitely adds plenty more base and adds pitch to the car when giving it the gas. If you're thinking about adding it on, do it. It sounds way nicer.

    Overall, just a great product. The crackles/pops/small backfires never get old and its a great first addition to your exhaust setup. Would buy from Nameless again!

  2. Pretty darn good

    Posted by on

    I have the 4” muffler with the 3.5” tips. They sound great, and for those who are wondering, the 3.5” tips look pretty close to stock if you’re tying to gauge the size. The 4” muffler is pretty loud when you’re really on the gas and pretty tame when you’re trying to sneak into the neighborhood. The cold start will be loud no matter what exhaust set up you go for, even on a stock WRX. I thought I should’ve gone with the muffler deletes for about a week after installing, but after living with the car for awhile the 4” muffler setup feels perfect. (It’s why you can never find them used)

  3. Love the sounds!

    Posted by on

    Just installed the 4” mufflers with double wall beveled tips on my 2018 STi yesterday. Absolutely love it. Made a great video of it too.

  4. Awesome! Not too loud not to quiet

    Posted by on

    Takes about 45 minutes job easy install. I got the 3.5inch single wall it looks great fills the bumper but not to close to melt it. On start up it sounds awesome! Then after 30 seconds it isles down and it sounds like it is stock lol. When driving going over 3k is when it starts to get loud and pops into upshifting and downshifting!

  5. Best Exhaust ever

    Posted by on

    I purchased nameless 5" muffler with 3" tip exhausts (used) and I had purchased all the nameless hangers to go with it

    It's an amazing sound!!!!
    idle sound is just a tad bit louder but when you're driving oh yeah you can definitely hear the rumble it's deep, it's beautiful, no disgusting rasp, no drone whatsoever, very beautiful sound and when you get on it my lord is it sweet.

    I got the 5" muffler as I will be purchasing a mid pipe + downpipe later on and wanted to compromise for the loudness that it's going to get later on.

    I highly advise you to get the hangers, they make a worlds difference especially with the 3" tips, it fits the tips really snug in the bumper cutouts and they're leveled better than stock exhaust. You can definitely tell the exhaust has been modified

  6. Loud enough for an old man

    Posted by on

    Car sounds much better over stock. Drone at highway speed is still noticeable. Not too loud to attract smokey's attention.

  7. Great Quality and Easy Install!

    Posted by on

    Purchased the 4" mufflers after much research and YouTube videos. Glad I picked them. Just enough sound without being overbearing. Makes the car sound a little deeper and throatier without sounding like a tin can. Shipping was super quick once I ordered (week or so). The quality on this exhaust is amazing, stainless steel and perfect welds. Installation was about 15-20 minutes (with a vehicle lift). Highly recommend and will purchase their products again!

  8. Quality

    Posted by on

    Nameless expertly provides build quality, aesthetics, and sound. The neochrome delete has most certainly enhanced my WRX to the next level of aggressive.
