Exhaust db reducing tips

[gt500nick]

Hi I'm looking for options to make my viper less noisy and pass noise tests for some track days this summer. I've seen a few things but I am slightly concerned they might not fit and it might have to be custom job.

Has anyone got any experience with baffles or similar options? Does it effect performance greatly? Demon tweeks have a few options bolt on but I'm not convinced on them any advice would be welcomed.

Cheers

Talk to Pete Ellis at PTR Exhausts in Brackley. He makes amongst other things, perforated inserts which got our Dallara F3 car within sensible limits for its first outing.
