86-91 Corvette 5.7L Cat Back Kit

The MagnaFlow 86-91 Corvette 5.7L Cat Back Kit (MPN 15658) is a direct bolt-on performance exhaust system specifically designed for fourth-generation C4 Corvettes equipped with the 5.7-liter TPI or LT1 V8 engine. This exhaust system is ideal for automotive enthusiasts looking to enhance their vehicle's sound and performance.

Constructed from mandrel-bent 304-grade stainless steel, this cat-back design replaces the factory muffler and rear piping while retaining the factory catalytic converter. The system is engineered to optimize exhaust flow and reduce backpressure, contributing to improved throttle response and engine efficiency for naturally aspirated engines.

Owners of 1986–1991 Corvettes will appreciate the straightforward installation process, which requires no cutting or welding as the kit bolts directly to the factory mounting points. This exhaust system is a valuable upgrade for those looking to maximize performance and sound without compromising the vehicle's original design.
