My system has 1 3/4 primaries, 2 1/4 secondary's and 2 1/2 system.
made 368bhp on rolling road so 3 inch should be fine.

Thanks

That's impressive on a single 2 1/2" system

It only cost me £80 for the Cosworth 3" system and it seems a shame not to use it!

EDIT to add

What spec is your Rover engine to make that figure ?

3 inch single exhaust - power limit ?
