stacks vs. normal exhaust.
Obviously im looking for the best milage i can get...like every one is. Well now I have 5" stacks with a 4" "y" pipe that attaches to the stock exhuast. Im getting tired of the stacks and I was wondering I if would see a benefit going from the stacks to a regular exhaust with a 4" downpipe and the rest 5" with no muffler or cat (single, NOT duals). Im also about to add a cold air intake and i currently have a superchips in there. If i wont notice much of a diff, ill keep the stacks, but if yall think its gonna help, ill go with the reg. exhaust.
