Does anyone know the interior diameter of a Corsa exhaust ~10-15cm back from the exit pipes? Thanks.

I doubt it is exactly as it's almost certainly an imperial dimension. 3" = ~76mm maybe?

According to the Corsa website the Viper exhaust is 3"

Standard pipe is 3" but where you are asking for is in an area where there is a bend, silencers and the flare out to the tips at 4" so could be anything, why do you ask?.

I would go and look but am not feeling too well at the moment so don't fancy tipping my head upside down for you, if you don't have the answer before i get over pig flu I'll take a look.

Thanks Dave. Don't bother having a look, I'll find out one way or another!

lol you caught me, i deleted my post when i realised you wanted the inside diameter, that's a bit harder to get without cutting or knowing the wall thickness.

I have brought standard 3" tube before that has been an exact match on the outside for the regular straight sections.
