How hard is a flo-pro 5" downpipe to install on the 6.4. There isn't that much room in there

I'm pretty sure the downpipe is only 4". Every flo-pro downpipe I've seen has rubbed the firewall. But it is a 2 piece design and not too hard to put in. I would suggest looking at the powerstroker67 4" downpipe, it's a better fitting design IMHO.

Did you dumb fit it first? what I mean is did you put it together and get it all in line then tighten up? make sure that ALL is loose then tighten. Might sound dumb but that is why you call it a dumb fit.

Thanks guys. I go pick the truck up on thursday and am just curious. Should I just stay with the stock downpipe and just do a downpipe back then

If my truck was off warranty then i would take the stock down pipe off, I would love to get rid of my stock down but it is a pain to get out and the warranty thing is the biggest for me. So if you dont have warranty then ya get rid of it!!!

Ya I saw one rub on one of rudys videos. So I guess I will just wait and see cause this truck does have the warranty but I'm impatient and we will see how long I'll let it stay lol
