richieg Posted May 18, 2012 Share Posted May 18, 2012 I've removed my stock exhaust and have a question regarding fitting the staintunes. is it necessary to remove the old silver coloured gasket? it looks as though the staintunes will not fit unless it is removed but i'm concerened about the exhaust leaking. The instructions on line also suggest using high temperature sealant on the mufflers - is this necessary as the second hand pipes i'm fitting don't look as though any sealant was previously used...

bayarearider Posted May 18, 2012 Share Posted May 18, 2012 I had not noticed a gasket at the mid-pipe / cat connection when I replaced the cracked mid with the new hanger design one. The bolted strap keeps it plenty tight. I did however use the high heat copper silicone sealer on both cans to Y pipe connection to get rid of a noticable rattle. Worked like a charm!

Pretty much the same here... just used a little sealant at the Y pipe connections and that was it. Link to comment Share on other sites More sharing options...
PACIFICMAN Posted May 19, 2012 Share Posted May 19, 2012 Same as above. Clamp the pipe, as is to the header/Cat. Use High temp copper(I used Permatex) sealant at the "Y" pipe muffler joints, Tighten bolts, let sealant cure per the instructions and ride.

richieg Posted May 20, 2012 Author Share Posted May 20, 2012 The staintunes is fitted - I used some loctite 5920 to seal the mufflers on the y pipe. Thanks for all responses. When assembling though I could not get the replacement passenger bolt through the exhaust bracket with mufflers attached so gave up in the end and used stock bolt. I think I read somewhere that this is no longer done on newer exhausts... Finally I can't remove one of the db killers - seems to be held in very securely.. any tips?
