Getting a new exhaust
I have a bone stock lg4, and I know that exhaust is the very first thing I should upgrade. If I keep my stock manifold, and replace everything else will I get more power, or is the manifolds the main restriction? This shop is giving me a killer deal. 300 for two borla mufflers and dual exhaust with a x pipe from the manifolds back. I just want to hold off on headers until I do my head swap.

Re: Getting a new exhaust
So what would be a good diameter piping for the dual exhaust setup? As for as smog regulations go, to pass the sniffer would I have to run dual cats?
