I have a 06 wrx with a Greddy TI-C exhaust. Recently I noticed some leaking noise coming out of the gasket and I think I narrowed it down to a couple of gaskets. The problem is that I don't know where, size, and what they are called. If anyone here know please point me in the right direction. Thanks
I think it's after the cat and between the mid pipe and the tail pipe. Just picture installing a catback exhaust, I believe one would have to be a oem gasket ### it connects to the cat and the other is aftermarket gasket ### its on the aftermarket exhaust.
It looks like Greddy makes two different versions of the TI-C cat back. The regular one tapers to 2.5" where it mates with the downpipe and the Competition version is 3" all the way through. It sounds like you either need a 3" 2-bolt flat exhaust gaket or a 2.5" 2-bolt flat exhaust gasket. If you're not sure what version you have, you might as well pick up one of each size since they're pretty inexpensive. Also, make sure you have good hardware connecting the flanges.
Well, I finally got time to look at what was going on down there and figured it out. It appears that i need a donut gasket. Would a stock one fit? or is there and aftermarket donut gasket that would work and where would i get one. Thanks
