Yeah, the leak sound is driving me nuts. My mechanic told me to bring it back to his shop here in Calgary. He thinks its probably the same leak that he tried to tighten down before. It's the 3rd try he'll need to fix this, so I'm starting to wonder if maybe its something else. The gremlins (rattles, leaks etc) in a heavily modified car can be enough to drive a guy nuts. The feel of a TWIN TURBO Z makes it all worth it in the end
Just a heads up to anyone buying the GTM 3" downpipes. They don't really mate up straight with the FI exhaust, so it takes lots of messing around. It sounds like others haven't had much issue installing it properly, but my mechanic is having a hell of a time with it. Fast Intentions includes a written warning in their 3" exhaust shipment warning of the fitment issue with the GTM pipes. Mine are way out for sure.
Tony - will Fast Intentions consider development of their own 3" pipes some time?
