Can anybody tell me, what the internal bore size of the HKS Downpipe and Super Drager II pipework is, as fitted to the Evo VIII FQ cars (non MR).
I didn't think the HKS system had such a small bore :shake: Maybe I do need to think of replacing the whole system thenlee5 said:Bin the HKS system to restrictive bore size they are 2 1/4 inch at cat, also they narrow in the back box to keep nosie down
Get a true 3inch like the magnex or blitz
