Soul Performance Catted/Catless Downpipes Chevrolet ZR1/ZR1X 2025-2026

The downpipe is the most restrictive section of a turbo exhaust, and on the Chevrolet C8 Corvette ZR1 / ZR1X it is the first place to look for more response and turbo sound. The SOUL Catted / Catless Downpipes open up the path right after the turbo with large-diameter tubing.

SOUL Performance Products designs, builds and tests its exhaust parts in-house in Willow Grove, Pennsylvania, and has developed many of them on its own track and street cars. Parts are covered by a lifetime warranty for street and track use.

Options on this page: Downpipe: Catless Downpipe, Catted Downpipe. Model: ZR1X, ZR1. Catted choices use high-flow catalytic converters for street use; catless choices replace them with straight pipe for maximum flow.

• Large-diameter tubing for less back pressure and stronger turbo sound
