This REMARK axleback kit eliminates the muffler canisters, and thereby unmutes the exhaust note. Produces a sporty and aggressive exhaust note. A cost effective way to inject more liveliness into your Lexus IS both audible and visually with the larger 4" tips.

Offered in four variants which differ in tip finish and construction:
FINISH
  • Stainless - Fully polished stainless steel to a high luster
  • Burnt - Stainless steel is treated to add a spectrum of colors ranging from gold, purple, and blue. This is achieved through a chemical process for improved consistency, and does require more care when cleaning, LINK
SINGLE or DOUBLE wall construction
  • Single Wall - just has implied, the tip consists of a single layer of stainless steel. In general the appearance is considered more sporty as the tips look larger since there is not inner wall. It also looks and is lighter in weight.
  • Double Wall - the tip has an inner and outer layer of stainless steel. In general the appearance is more luxurious as the tip appears thicker since there is an outer and inner wall. This also means the edge looks and is thicker.
There is no difference in sound nor performance between the different versions of the tip design. For more images and diagrams of the difference in construction, click this LINK.

Our kit is a simple bolt-on replacement for the OE mufflers. No modifications are required, does not trigger any check engine lights, and does not effect vehicle emissions. Installation is simple and straight forward. No cutting, no welding, and the factory exhaust can be reinstalled easily anytime. Full 304 Stainless Steel construction, and fully TIG welded by our expert craftsmen. Kit includes both right and left side, as well as required hardware for installation.

 

This product fits different models of the Lexus IS. It will sound different based off the engine size and type. In general, the IS300 sounds quieter due to the nature of a 3.0L turbocharged engine. The larger 3.5L V6 models will generally sound louder. 


* Does not fit with 2014~2020 Lexus IS models.

Love it!

So glad they added the video cause I definitely wanted to make sure the sound is right. Didn’t want something obnoxious but this has a very nice growl and for sure made my car a more fun ride. I have a 22’ IS350 and I loved my car before but this made the experience twice as fun. Definitely recommend it

Great Exhaust

I recently installed this axel-back exhaust on my 2021 IS350, and it has a nice deep tone. I didn’t want a high pitched sound like you get from a straight piped exhaust, but this sound is perfect. I installed it myself, took a bit longer because of limited space working underneath but I managed to get it done in a couple hours. Driving around there is a little bit of drone from 2-3k where you would be cruising. I know some people get annoyed by that, for example if cruise on the highway for extended period of time. You learn to get used to it and I always have music playing so it’s not a big deal. Overall great exhaust. 9/10
