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.

Easy to install and the best sound ever.

Excessive amount of drone.

The excessive drone in the cabin at all RPM ranges is truly unbearable and ruins the entire driving experience. Even with a different muffler, the drone is still overwhelmingly present and makes driving extremely irritating. Unfortunately, I am now looking for a way to uninstall and revert back to the stock setup. I even tried wrapping the exhaust with manifold wrap and steal their drone is unbearable. . .

Nice sound, discolored pipe

Sounds good. One pipe is noticeably less “gold” in color than the other.

awesome

sounds great not too loud but definitely adds some noise, sounds great on my 4cyl is300, has a nice deep tone and weight reduction and larger pipes makes the car feel a little bit quicker, overall great purchase
