First I think you should get a new exhaust guy.
If that were true then there wouldn't be a point of Dodge making the side-pipe for the SRT-4!
A tight, curvy pipe is a restriction, 'nuff said. I wouldn't suggest a 3" pipe unless you plan on 400+ hp and understand what it'll take to get that high in hp.
The other thing is that you can always upgrade later, suggesting high flow cat and larger downpipe. Then just purchase a collector and weld the whole thing up nice and tight and nobody would be the wiser.
And the reason Greddy and Apexi sell so much of that stuff is simply marketing. Most racers fabricate their pipes. They don't get them predone.
