Your Mustang GT will breathe in all the air it needs if you're modifying it for track racing as these Long Tube Headers from Borla were designed to release the restrictions the factory stock manifolds place on your V8. These Long Tube Headers have 1-3/4" Primary pipes and 2-3/4" merge collectors. The catalytic converters are removed when using these headers because they are intended for competition use only and are designed to be used with Mustangs equipped with extensive performance upgrades and a custom tune. This is a race header and not recommended for emission-controlled vehicles.
