I want to run a 5" straight pipe on my truck I dont care if it drones or if its too loud thats what i want. will it make that much of a difference over 4in i want to run 5" in a stack set up. tell me how it sounds is it really deep like a big rig waht im gettin at is it worth the money will i see a big difference??

 

I put a 5" on my truck a while ago,& like it.It's LOUD! Even with the big muffler that came with the kit it drones heavy.But I lost about 100* EGT right off the bat,& spool up is faster.If you aren't worrying about the noise then it'll work for you.BTW. My truck doesn't have any fuel,(YET) either.With the mods I see on your sig it shoulg really go.Good Luck.
