I know others have done it too but just an FYI it sucks!!!! I was going around a corner designed for like 15mph at around 50mph and gave her some gas around the curve and the boost was at like 20psi and bam there she went. The cat pulled out of the turbo flange and the car went to shit. I stopped a couple miles down the road and sure enough it had seperated. I took it to the local Minekee who welded it back up nicley and did some other spot welding on the exhaust where the Nuespeed guys missed some spots. :shock: Works beautifully now. Just don;t know how long it will hold up. Are you guys replacing the cat after this happens or what?
