I didn't want to hijack tectons post and I did a search looking for the answer but couldn't find any thing that addressed this in depth. If I run the outlet in front of the rear tires, Will it be to loud/have to much fumes in the k5 with the top off/enough room under the truck to make the bend that early? I will be putting the 40 series flows in it with all new 2 1/2 pipe. Should I dump them down/90 degrees out or angled? Thanks for replies. btw, I haven't bought the flows yet and I'm looking for that "hollow rumble" noise when idiling and that nascar sound when it gets romped. Is 40 series the way to go?
