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.

  1. 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.

  2. 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 !

  3. 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.

  4. 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

  5. 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.
