Default Re: How do you port and polish

Ok next question. It applies to porting so ill post it here.

After porting, has anyone used a slightly larger diameter exhaust pipe? I can't use an expansion chamber and still keep the same specific appearance that I'm going for. So I'm trying to go for as unobstructed a flow as possible.
Is this a good idea?...or is untuned back pressure a good thing?
