I know nothing about exhaust systems so please bare with me. Iv done some searching on this site and still am unsure of some thins. I have a 2004 f-150. i want to get as much performance out of the exhaust i can with as little cabin drown as possible but i still want to have a good growl outside of the truck. im thinking either 18 or 24 muffler.

1 Whats the sound differents if i have single in single out, or single in dual out.

2 What size pipes and tips should i get.

Any help would be appreciated
