jse Posted June 10, 2008 Report Share Posted June 10, 2008 i recently replaced the 2 o rings that sealthe header pipe to the middle box, but the exhaust is blowing there again. any thoughts? Sometimes the alignment makes it hard for the special mid-muffler o-rings (D shaped) to do their job. I always use some hi-temp Silicone sealer on the header pipe before sliding it in and then wipe away the excess, leaving a neat radius of it to seal the pipe/mid-muffler junction and let it cure overnight. When using Silicone sealer, always make sure the surfaces are clean. Jon Quote Link to comment Share on other sites More sharing options...
