Provides an Aggressive, Throaty Exhaust Note for your Subie

Adding a hyper-aggressive exhaust note to your mighty Subaru WRX or STI doesn’t mean you need to have a painful install or put a dent in your wallet. The Remark Muffler Delete Axle-Back Kit for 2015-2020 WRX and STIs features a high-quality construction and completely deletes your STI or WRX’s rear mufflers to generate a big, new exhaust note for your awesome Subie build. The Remark Axle-Back Muffler Delete Kit is extremely easy to install and has a much lighter weight than the stock muffler assemblies to help your fast Subie shave off a few pounds. The Remark Axle-Back is topped off with quad exhaust tips that are available in both a natural stainless steel finish or a blued finish for a high-performance look.

304 Stainless Steel Axle-Back with 2.5" Diameter Tubing and 3.5" Tips

Despite not breaking your bank, the Remark Axle-Back Muffler Delete Kit is made out of quality materials and was carefully designed for a perfect fit on your custom WRX or STI build. Each Axle-Back System is made using 2.5" diameter tubing that’s all precisely mandrel-bent to give your Subie a great fit. The entire system is made out of 304 stainless steel that’s resistant to corrosion in practically any climate or application. The axle-back system features quad, slash-cut, single-wall exhaust tips that are available in your choice of either a standard stainless steel finish or an aggressive blued finish. Each kit installs right into place of your WRX or STI’s stock axle-back without any trimming, cutting, or drilling.

    this is so easy to install and worth every penny. the sound i got for such little money was quite impressive, and saves me some cash for other mods. definitely recommend.

  3. worth it for the money.

    By finn Caldwell March 30, 2023

    definitely worth it considering how cheap it is. loving all the sounds and noises, and recommend to anyone who needs an exhaust for cheap.

  4. Good quality exhaust terrible fitment

    By Hunter April 23, 2022

    Overall I am satisfied with this exhaust. I have owned it for about a year at this point. Great quality welds and fits like it supposed to overall. However the gaskets or something was not fitting properly and it was leading to a terrible exhaust leak. No matter how tight I tightend(I even snapped a bolt in half) the leak would not go away. I bought some grimmspeed gaskets and it still leaked. I had to double up the gaskets to stop the leak and a super annoying puffing sound coming from my car. Overall I would still recommend this exhaust but if it ends up leaking just know you will need some gaskets.

  5. Get rid of the wimpy stock sound

    By Tom July 21, 2021

    Just installed these on my 2017 WRX. This is how the car should sound. Had an issue getting the left side stock muffler off the last hanger and one of the new bolts was cross-threaded so I used one of the stock bolts. Other than that installation was quite easy. I did it by myself with no issues. I did not have any problems with clearances when tightening the bolts. I have about an inch from the cutout on the top and 1/2 inch on the sides. I was able to just bolt right up. I suggest spending the extra money to get the double wall, they look great.

  6. Beautiful piece of metal!

    By Josh April 10, 2021

    Best decision I’ve made on my ‘20 wrx to finally hear that boxer engine. Installed by myself with no trouble. For the short time that they’ve been on, I couldn’t be happier with my purchase!

  7. Best bang for you buck

    By Alex April 18, 2019

    Taking off the old mufflers is kinda difficult, just used some wd-40 and the bolts came right off along with the hangers. After that I had no problem putting this exhaust on, the fitment was perfect. The sound is way louder than stock. Cold starts will wake up a neighborhood, but idle is fine and can't hear it. For casual driving the noise isn't that bad but if youre sending it the car behind you is gonna hate you. I have a wrx so the FA motor is rich in fuel so I can get a lot of backfire out of it inbetween shifts and downshits. And plus when you rev you can hear the turbo whistle out the back.

  8. 3/5

    By SRG April 2, 2019

    Its been two months since I've installed these on my 17 WRX and they absolutely sound great! Droning at highway speeds can be intolerable; especially at +70mph. I see some rust developing on these already (Boston climate) Interesting to see how ling these will last !

  9. Just the right amount of loud

    By Tyler January 4, 2019

    Installation of these is very straight forward. A can of penetrating oil for the bolts and some wd40 for the hangers will make your life A LOT easier. As for the sound: there is a very slight drone around 3k+ but its very minimal. At 70mph and below its nice and quiet. Cold starts are pretty loud, but once the car warms up it has a nice aggressive sound without being obnoxious. Overall I would recommend.

  10. Bang for your buck

    By Thor July 11, 2018

    I bought these in March, just the muffler delete sounds amazing, no drone, not too loud but definitely noticeable, a great addition and the price was very fair

  11. Awesome sound and look!

    By Tyler June 19, 2018

    Couldn't be happier with this. I get comments all the time about the good sound while driving, the blue flame tips, and being able to hear the turbo noise at the back when revving it.
