MacLGT-B Posted November 8, 2006 Share Posted November 8, 2006 Took the Spec.B to Stage 2 with PERRIN's Up & Down Pipes and their TMIC with a TDC ProTune. The install went well, We used all new gasket, but I didn't realize I would need a 3" flat gasket to replace the donut gasket that attaches the down pipe to the mid pipe. Does anyone know where I can pick up one locally? . . . Mac Link to comment Share on other sites More sharing options...

rc0032 Posted November 8, 2006 Share Posted November 8, 2006 You dont need a gasket. Did you read the instructions? Flip over the donut. Link to comment Share on other sites More sharing options...

PLTek Posted November 8, 2006 Share Posted November 8, 2006 if you are mating the 3 inch flat flange of the perrin dp to stock exhaust, thats what you will need to do. If you are mating it with Perrin 3 inch catback, you would need a flat 3 inch gasket You dont need a gasket. Did you read the instructions? Flip over the donut.

MacLGT-B Posted November 8, 2006 Author Share Posted November 8, 2006 if you are mating the 3 inch flat flange of the perrin dp to stock exhaust, thats what you will need to do. For now that's what I'm planning on doing. Later on I'll upgrade to a 3" CBE System. Link to comment Share on other sites More sharing options...
antny Posted December 18, 2006 Share Posted December 18, 2006 Question for you guys. I am running the perrin DP with the stock catback and have a nasty leak from flipping the doughnut. Will it leak if I flip the gasket back the original way? or should I just crank on the nut some more? Link to comment Share on other sites More sharing options...
MacLGT-B Posted December 18, 2006 Author Share Posted December 18, 2006 I believe it would leak even more. I also had the leak after I flipped the gasket. Locally I couldn't find that 3" gasket nowhere, so I picked up the biggest gasket they had 2 3/4" (2 of them) and used that with the donut gasket and it worked. I eventually picked up the PERRIN Mid & Y Pipe which I requested all gasket be included. Everyone upgrading to a 3" Downpipe should insist the the 3" gasket be included.

Boostjunkie Posted December 18, 2006 Share Posted December 18, 2006 I had much better luck getting a good seal between my stock catback and Perrin DP with a 3" flat gasket than flipping the donut. I'd also recommend swapping out to regular nuts and bolts and getting rid of the spring bolts. Try Napa Auto Parts or a heavy truck supply shop for the 3" gasket. They are much more likely to have one than a regular auto parts store, or even most muffler shops. Link to comment Share on other sites More sharing options...
whitetiger Posted December 18, 2006 Share Posted December 18, 2006 +1 for getting rid of the spring bolts. eventually they will rust and break anyways. Link to comment Share on other sites More sharing options...
automaticsti Posted December 19, 2006 Share Posted December 19, 2006 what about cobb DP and perrin catback what should u do with the gaskets in that case? Link to comment Share on other sites More sharing options...
whitetiger Posted December 19, 2006 Share Posted December 19, 2006 use the donut gasket. Link to comment Share on other sites More sharing options...
PLTek Posted December 19, 2006 Share Posted December 19, 2006 you will be fine here, cobb dp takes a donute gasket which will seal a 3 inch flat flange fine. what about cobb DP and perrin catback what should u do with the gaskets in that case?
