hey guys, i was wondering if it is better to have more backpressure or less backpressure to make the most power. this being said what would be the best setup to run on my formula. longtubes into 2 1/2" or 3"? straight piped duals into mufflers or straight out no mufflers? headers then single pipe with mufflers? what is the best way? thanks and price isnt an issue..
