GrandPrix34 Posted July 20, 2004 Report Posted July 20, 2004 If so then the inner flow path of teh downpipe is really 2.25...which suxs! I am thinking of upgrading the downpipe as soon as it is confirmed that it is infact doublewalled. If not, well then it stays! Quote

mfewtrail Posted July 20, 2004 Report Posted July 20, 2004 Mine is, not sure about yours. Go to a 3" one anyways! He doesn't need a 3'' on his 3.4, 2.5'' actual inner diameter would be ample. Quote
