Exhaust Muffler Quad Tips for Lexus IS300 IS350 (2017-2020)

Direct-Fit Quad-Tip Exhaust Muffler for 2017-2020 Lexus IS (8AR-FTS/2GR-FKS / XE30)

What It Does: Replaces the restrictive factory muffler section with a high-flow dual-walled quad-tip configuration to reduce backpressure and enhance the rear aesthetic profile.

The Stock IS Weakness

The OEM Lexus XE30 exhaust system is engineered for maximum NVH suppression, utilizing heavy, baffled mufflers and tucked single tips that stifle the acoustic character of the 8AR-FTS and 2GR-FKS powerplants while creating a bottleneck in exhaust gas velocity.

The Engineering Solution

This system features 2.5-inch diameter mandrel-bent piping to maintain consistent exhaust velocity and 3.5-inch dual-walled quad tips for heat dissipation and aggressive styling. Designed as a direct bolt-on for the OEM mid-pipe, it utilizes factory-style hangers for a precise fit without the need for welding or custom fabrication.
