My track-proven Silenced De-Cat Pipe(SDCP) using modern fire-arm silencer design to help reduce drive-by noise at track.

Using a series of mini chambers with different volumes and varied, angled baffles to enhance noise-cancellation characteristics. They also maintain a high gas-speed through the silencer - important for exhaust scavenging at the cylinder head. If you come across a SDCP with a large, hollow chamber be aware that's not good for performance. Or,  if you are really stupid, you smash out the factory ceramic catalyser to 'improve performance'.

This 2bular SDCP is zero maintenance! - no packing materials to burn/blow out and it is designed to withstand the excessive engine/transmission movement these cars are known for.

I use a factory-style doughnut gasket cup and a reducer to the correct pipe diameter - 63.5mm (2.5"). All TIG-welded into one strong unit. No-one else bothers to do this work. You cannot swage a 63.5mm diameter pipe out to the gasket cup diameter, so other firms use a larger downpipe, either 70mm or 76mm(!) - to the detriment of gas-speed and engine performance. No TIG-welding, just a loose flange. Very sad - very cheap. 

This layout fits to the factory manifold flange and INCLUDES A NEW DOUGHNUT GASKET.
