Lowest Price GuaranteeBlackHeart Header-Back Exhaust System1970-1974 Chevrolet Camaro and Pontiac Firebird LS Swap 3 in. Tubing Aggressive to Moderate Sound Stainless Steel Natural Finish Sold as a Kit
Dropping an LS into a second-gen F-body leaves you with nothing behind the headers that fits, so the exhaust becomes a fabrication job unless someone has already done the routing. This is the whole system from the header collector back in 3 in. stainless, mandrel routed around a chassis it was never designed for.
Hooker 70501386-RHKR BlackHeart Header-Back Exhaust System Features:
- Fits 1970-1974 Chevrolet Camaro and Pontiac Firebird with an LS engine swap.
- Complete header-back system, no fabrication needed between collector and tailpipe.
- 3 in. tubing throughout.
- Aggressive to moderate sound level.
- Stainless steel construction in a natural finish.
- Sold as a kit.
