Hey i have question for my 2002 ford f150. I have flomasters and little gibson tips and I wanted a more throater louder sound and I was wondering without getting new cats or doing anything else to the exhaust would tips do that? and if so how big should i get.. i want to get the 4 inch tips, but would that be a problem with backpressure..im not too good with knowing what backpressure is. but if anyone could help that would be great. I want to get the 18inch by 4 inch or 3.5 inch....not sure...help please

 

I don't think the tips are going to have any real affect on back pressure (or anything else for that matter except sound). I would go for it!

 

I have 3 1/2" tips on mine and its deep and sounds real good, i belive their 18" long
