Description
If you’re running a small-block Chevy LS in a dirt late model, exhaust scavenging directly impacts your power output and throttle response. The Beyea Tri-Y DLM 525 headers are purpose-built for crate engine applications, with optimized primary tube sizing and collector design that maximizes exhaust velocity across your RPM range. This is a complete, bolt-on solution that eliminates guesswork and delivers measurable performance gains without fabrication headaches.
