My car is a cruiser, I'm going to be running duals from factory manifolds & I have no plans to do any kind of racing, but I also want to get as much power out of what I have; so which one do I want to go with?
IMO, I would consider headers before beating yourself up over x or h pipes. You're likely leaving 25-50 HP on the table running the stock manifolds. As far as the rest of the exhaust system, just remember low restriction.
