Our midpipe kit for the Lexus IS (V6 RWD) features dual high flow EPA approved catalytic converters, and dual straight through resonators. Improves exhaust gas flow over the OEM midpipe which is smaller and more restrictive. 2.5" mandrel bent piping with H-pipe design.

Each kit utilizes two 400 cell, metal core, high flow catalytic converters. These units are EPA approved.

As with most high flow, less restrictive exhaust components, the additional of this midpipe kit will increase the exhaust volume whether you are pairing with OEM mufflers, or aftermarket axleback kit.

Ryan X. ★★★★★ Oct 18, 2026

The install was straightforward on my 2016 IS350, and the dual resonators actually make it sound deeper without any annoying drone on the highway. Butt-dyno feels like the car breathes easier past 4k rpm, which was exactly what I was hoping for.

Hazel ★★★★★ Oct 17, 2026

The high-flow cats paired with those resonators really opened up the exhaust note without making it obnoxious. I can feel a noticeable difference in throttle response during daily driving, and the build quality was solid enough to bolt right up to my IS350.

Edward H. ★★★★★ Oct 12, 2026

Sound difference after swapping to this midpipe was immediate on my IS350, deeper without being obnoxious at highway speeds. The dual straight-through resonators keep drone out of the cabin, which was my main worry. Fit was spot on and the high flow cats didn't throw any codes.
