Is there a way of working out what diameter exhaust is needed?
I've been told I need 3" but this was assuming I had an internally gated turbo, what diameter could I get away with if it was an external gate and had a screamer? also what diameter would said screamer need to be if the exhaust was 2.5/2.75"?
Cheers
