My pipe doesn't seem to fit very tight in where it connects to the header so i was wondering if i could put some of that hi temp sillicone gasket maker around the original gasket so when i put it on it will hopefully make a better seal than what is there at the moment. It's the skyline v12+ if it matters. Would that be ok? When i want to take it off though i will have to replace the gaskets i suppose

I don't want to ruin it i only just bought it 2nd hand

cheers
