The Supreme SP system for the Lexus IS300 sedan marries timeless design with a sonorous and refined acoustic profile. The oval SP muffler not only ensures ample ground clearance but also promotes superior exhaust flow that complements the robust 2JZ-GE inline-6 engine of the USA-spec model. The substantial 3” piping diameter positions this system as an excellent foundation for further modifications or forced induction setups. True to the GReddy tradition, this Supreme SP exhaust is fashioned from hand-welded 304 Stainless Steel, ensuring durability and is accompanied by a Limited Lifetime Warranty for peace of mind.
