- Tue Jun 01, 2010 6:36 am #198066 hey guys problem again...later on today i started hearing like a hissing sound whenver i would hit the gas...it sounded like a exhaust leak, i have a 4-2-1 header and i think its coming from where the header and the downpipe meets...i might think its the gasket on the downpipe is wasted...cause when i was looking at it, like around the downpipe were the bolts are at its kinda like it has like rusting or burnt looking. so i might think its the gasket. and while i was looking at it i saw that it had 2 gasket on the downpipe. doesnt it only suppose to have 1 not 2? but yeah, and another question does it suppose to have a gasket were the downpipe and cat meet suppose to have a gasket too or not? like a ring of some sort? if you guys could help me get that annoying hissing kinda sound i would really appreciate it...

- Tue Jun 01, 2010 1:02 pm #198085 You're correct on everything. I don't know why there would be 2 gaskets though... I'd replace the one that is leaking and worry about the double layered one if it ever starts leaking
