2.5 complete exhaust VS a 3.0 complete exhaust
i built a fairly moderate 360 with intentions of adding a power adder. used TTI headers, x-pipe, and 3 inch exhaust.
if this is primnarily a street car, go with 2.5. youll be much happier. the 3 inch is tough to fit without heat and rattles, is louder, and kills ground clearance.
also be honest about wether or not youll actually be stepping up the motor later. that way you only have to buy one system.
im still looking for someone to trade my 3 inch with a 2.5. im never actually going to go power adder, and need the ground clearance, not the extra exhaust flow. im making 425 at the rear wheels, by the way.
