Can't seem to find much info about what exhausts people are using on their turbo converted 325s. Obviously the downpipe from the turbo has to be custom but what about the rest of the system.

I'm hoping to to get a little over 300bhp from mine so I need to make sure I won't be restricting the flow but at the same time I don't want to have a stupidly loud exhaust if I can help it.

Any help is appreciated
