Is there any major difference between a 24"x3" Tip vs. a 18"x3" Tip. Any performance difference or sound difference. I have the 4.6L so backpressure means everything to me. Will the 24" tips reduce backpressure more than the 18"? Thanks for any help.

 

tips dont really make a diff in backpressure, the dia.of the pipes how long they are is what make up backpressure. tips might make more of a lower sound or throw a sound diff. kinda like a megaphone.
