3 inch exhaust with manifolds??

I put 3" exhaust on a street driver once and will not do it again.
Wasn't worth the expense for me since I'd didn't make the car any faster
than the 2 1/2" pipes.
I was using headers. And the pipes exit in front of the rear wheels. Very loud
with the 3" . the 2 1/2" weren't exactly quiet.
If I was running a supercharger 3" would be a go for sure.
