imma get me a t-56 in mah fox body

so im goin all out...dropped a good $10k on ol' Red 6 months ago...n now my tranny goes...so a t-56 is wat im goin 4...gotta do it big...i was gonna go viper t-56 but i hear the steeper gears could leave my rear end @ the line if im not careful...so im goin with the DD perform. custom t-56 kit with the plain ol gearing n call it a day. the problem is, im bein told my exhaust(being that i have a good ol pro-chamber) that the new crosmember might have some problems with my exhaust n some extensive work might need to be done...can anybody back this up for me, is there anything that might b effected or should i b good.

P.S.- i was just curious as to anybody thats a up n comin mustang driftr...ive been into drifting since before it got big in the states...about 4 years now im thinkin...n have had my mustang for two, n as soon as i got it i told everybody it was goin to be a drift/grip mustang...no straight line for me, i love the curvies...but is there anybody else out there who has a story, maybe get sumthin started?
