This REMARK axleback includes two high flow, straight through design muffler canisters.  It produces a deep sporty exhaust note. This is ideal for those wanting an exhaust note without it being overbearing, and the primary sound heard from inside the car. There is a nice balance of a deep exhaust tone and the engine sound. We consider the sound volume quite mild, and feel it sounds like something you could purchase at the dealership as an optional performance part. 

Offered in two variants which differ in tip 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.
Both variants are Double Wall construction - the tip has an inner and outer layer of stainless steel. In general the appearance is more luxurious as the tip appears thicker and more pronounced. From the rear, the tips appear to have more of a shine due to the added surface area on the tips edge.

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.

Worth the money

I love how my car gotten a deeper growl, and combbning it with my after market midpipe it wakes the car up

excellent quality

No drone and it is refined, I would have been more pleased if it had a little more sound.
