Hey, im goin to be getting a 4in or 5in exhaust very soon. Im just confused between which one to get. I really like the way a 5in sounds. But i heard that you cannot fit a 5in down pipe. Is that true?? Would I have to go 4in downpipe then go into 5in??
Thanks

Yeah the 5" dp doesn't fit. A 5" system has a 4" downpipe that adaptes into 5" Six inch systems may also be the same, I don't know

cool.. thanks!!
will i loose any power with a 5in?? All I have is a intake and 3in straight now, but i think maybe the fuel plate is forward.. but im not sure.. i have not messed with it since i bought the truck and it seems pretty quick. Soon im going to check and see if its forward, if not im going slide it all the way forward. I also just bought a boost elbow on ebay!!

No. The only drawback to an overly large exhaust on a turbo engine is slower spool up, but since its a 4" dp you won't have that problem
