De-cat....how do I prevent the buzzing

[rt172]

Ive got a straight through de-cat pipe to fit to the Willy. When I had it on before it buzzed like a b*****d bumble bee which sounded sh*te and was generally annoying. Is there any way I can re-fit the pipe without it buzzing? Is there some sort of gasket I can put on it? Special Anti-Buzz exhaust sealant? Anything?!

I just fitted two new gaskets and sealed around them with some exhaust putty. No problems so far!

Simplest solution to that is buy a silanced one! thats what i did cuz i got that buzzing too with the straight thro that i originally had!

I got a devil straight thru and de-cat put gaskets and putty on just rumbles when ticking over doesnt buzz or anything only noise you can hear is the injectors i think or fuel pump like a buzzing noise from the exhaust tailpipe

Dont want to fork out for a silenced de-cat if I can get away with the straight through. Where would I be best getting the gaskets and sealant from?

Any local exhaust specialist. It will cost under £10 to have it done - my local Kwik-Fit did it for free. Youll have some come-back if they dont get it right too.
