74-80 Corvette Cross member Back Exhaust

The 74-80 Corvette Cross member Back Exhaust by Pypes Performance Exhaust is designed for C3 Corvette owners who want a direct bolt-on performance upgrade without extensive fabrication. This system replaces the factory rear section, allowing you to retain your existing mid-pipe while significantly enhancing flow characteristics and sound.

Constructed from mandrel-bent tubing and precision-welded, the Pypes system ensures proper diameter transition and minimizes turbulence, which are essential for quality performance exhaust. The crossmember-back design focuses on replacing the most critical component for performance: the section behind the transmission support, addressing bottlenecks created by factory piping.

This exhaust system is particularly beneficial for those restoring a classic Corvette or building a weekend cruiser, as it optimizes exhaust scavenging in the rear axle area. With straightforward installation requiring no cutting or welding, it is specifically engineered to fit the C3 platform (1974–1980 models) and is compatible with both Big-Block and Small-Block engines.
