5in. turbo back?

[cherryunit]

is it a pain to put 5" turbo back exhaust on a 7.3? and are 7" stacks with fappers a good idea?

You wouldn't really have enough pressure to keep flappers that big open at an idle - it'd be a ting ting nightmare. You may want to look into some turn outs if you're trying to keep the water out. The 5in won't be bad at all with a 4in downpipe.

haha... 7 inch... that would look cool.. i wana see some pics of someone who has that. 5" cant be that bad.. alot of people have it. but i wouldnt know. i just straighted mine

you cant fit a 5inch from the turbo back, you can only fit a 4inch down pipe then go to a 5inch. I know on the 99 w/ an auto trans that 4inch gets tight in some spots around cross members. But running a 4" DP then to 5" as soon as you could to 7" stacks would sound great. Good Luck

You're right, a 5" down pipe will not fit on almost all the fords...just not enough room. Here is a picture of a Superduty with 7" bullhorns I belive.

Yeah 4" dp is as big as you would want to go.

Is it just me or would those stacks look better as mitre cuts.

[crzycowboy]

To each their own. I personally like the Aussies, then the miter cuts. But thats just me. 6" aussies I think look killer.

[Farmboy444]

yeah i agree a mitre would look better, i almost want to say those stacks look to big. Ive got a 6" tip on my truck and its huge. dual 7" stacks would be loud as hel.

The more I look at the more it grows on me. I'm not real big on stacks though. It looks better than running them outside the bed.
