1995 F350 7.3 Powerstroke Stage I Injector Revs to 3k

Turbo definately spools faster now. MPG's went up about 1 mpg, but I already had the cat removed so didn't see a big improvement.

A 3" downpipe is all that will fit without some major firewall work, plus there are lots of OBS 7.3's making over 400hp with a 3" downpipe. And it's a lot better than the stock "pancake" pipe.

@JackieLulu did you notice a good power or mpg or turbo spool increase with the 3in downpipe compared to stock

REALLY ned that 4" down pipe. Your exhaust is only as strong as its weakest link. Just my .02
