Product Details

The GReddy Revolution RS cat-back exhaust system for your 2001-2005 Lexus IS300 is constructed from polished SUS304 stainless steel, a material known for its strength and resistance to corrosion. This exhaust is designed to replace the factory system from the catalytic converter back, aiming to improve exhaust flow and deliver a more aggressive sound profile that complements the IS300's inline-six engine.

This system features a dual-muffler design, with each muffler measuring 115mm in diameter, and dual 80mm polished stainless steel tips. The larger diameter piping and less restrictive mufflers help reduce backpressure, which can lead to a more responsive feel and a noticeable change in the exhaust note. Installation is intended as a direct bolt-on replacement for the stock exhaust, simplifying the process for those looking to upgrade their IS300's performance and appearance.

When installing this cat-back system, you can expect a deeper, sportier tone compared to the factory exhaust. The SUS304 stainless steel construction means it's built to last and resist the elements, keeping your IS300 looking and sounding great for years to come. This exhaust is a popular choice for IS300 owners seeking a well-built, performance-oriented exhaust system that offers both an improved auditory experience and a distinct visual upgrade with its polished tips.
