Yiu know what, now thinking of it. I cut the resonator off on the mid pipe and the end that's tappers to 2.75" and made it complete 3" straight pipe so that's probably why.
I need some clarification! hks catback tapers to 2.75" at the midpipe flange to match stock cat. if I end up getting 3" downpipe and test pipe...can I still run the 2.75" taper or do I have to change to full 3"?
