Advice please

MY00 Turbo

I have tried most exhausts and I won't bore you with my preferences but can I have a quick show of hands on these options?

I am going for a full decat, currently I still have a catted downpipe.


Firestorm backbox or
Prodrive back box

I have the firestorm at the moment and I know it sounds great but I am looking for power gains over noise.

So if you think the prodrive rear box is too restrictive I won't bother.

A full decat system with a firestorm shouldn't be much louder on idle that one with the primary cat anyway should it?

Thanks
