Hmmm, did you install the gaskets that came with the pipes?

Interesting I am sure my Corsa Tourings did not come with gaskets when I installed them back in 99 and my C5 does not hiss

What kind of Corsa's do you have ?

Touring, I think the hissing sound is coming from the passenger side of the car, at the back of the motor? Sound is hard to pinpoint [at 50 to 60] but I think it is by the passenger floor board.
