172 manifold diameter

[geesus69]

does someone know this off the top of your head? or can someone measure it for me?

ive got a funny feeling its 2 1/4" as i measured the ph1 cat ive got and thats 2 1/4", however i measured the daimeter of the ktec exhaust that came with the valver and thats 2", is this going to cause any problems with gas flow/ back pressure?

cheers

its not a massive problem, im running a 2" system, pulls like a train to 135 then stops lol

its just for the downpipe, going to get some sections to weld up, comes as either 2" or 2 1/2"

very nice, i want a different system but costs certainly wont allow that just yet
