Sealing exhaust
Posted: Sat Apr 13, 2019 10:53 am
Over the last week or two I've dismantled the exhaust system and taken the manifolds off of my S4 trying to track down the cause of a leak. I can hear it on acceleration and I get some popping on slow-down. I've now cleaned everything up, checked the fit of the various bits, bought new clamps / manifold gaskets and now it's time to reassemble it.
My question is which sealants to use. I've a choice of high temp silicone or the traditional firegum style. Should I use the same stuff throughout - if so, which? or is one better than the other at certain joints?
