Emily T. ★★★★★

Was a bit nervous about the install, but this converter bolted right up to my '89 without any modifications needed. The check engine light has stayed off since I put it in, so that's a relief.

George ★★★★★

The mandrel-bent tubing allowed me to keep the stock exhaust routing without any hassle. Bolted right up to the 1988 Corvette’s factory mounts, and no check engine light after a few days of driving. Feels solid compared to the rusted-out original I pulled off.

David ★★★★★

Bought this direct-fit converter for my C4 and the install was straightforward, everything lined up perfectly with the existing hangers. No check engine light after a week of driving, and the exhaust flow feels stronger than the old clogged unit.
