63,5mm (2,5") Cat-Delete Pipe – Racing Catalyst Replacement

Cat Delete Pipe 63.5 mm (2.5") – Racing / Dyno / Off-road

The 63.5 mm (2.5") cat replacement pipe is a straight-through hollow unit designed specifically for motorsport use. It eliminates the flow restrictions of the OEM catalytic converter and allows for a significantly increased exhaust gas volume – ideal for turbocharged high-performance engines.

The reduction in backpressure helps to improve turbo spool-up, reduce exhaust gas temperatures at the turbine, and enhances overall throttle response and horsepower output. The free-flow design is ideal for drag cars, track tools, tuning projects and dyno tuning.

Made from high-temp steel, the shell is engineered for durability and long service life. With its universal form factor, it can be integrated into nearly any 2.5” exhaust system – via welding or clamping, depending on your setup.
