i recently bought a 5" turbo back mbrp kit and the front pipe is only 4"...it looks like there might be some clearance issues with true 5"...wondering if mbrp or anyone makes a true 5" turbo back kit, or if u can buy just that 5" front pipe?

watching i was thinking of asking the same question..i think to tell you the truth the whole 5" thing is more of a looks/sound thing tho ive read up here anyway the 4" vs 5" isnt any difference in performance but i would like to know if there is a full 5" system excluding the turbo direct pipe.. and sorry not to hijack this thread but anyone know of a 4" turbo direct pipe on top of it?

Clearance is an issue. I dont know of anyone making a 5" front-pipe.

i know if they wanted to they could, the only thing that would need to be modified/removed would be the hanger on the side of the trans.

yea cuz the kit i bought from a vendor on here is sold by mbrp as 5" turbo back but the front pipe is only 4"...which in my book should be called something else...i bought it for the sound and look, although my egts dropped a bit

ALL 5" full systems use a 4" front-pipe.

Also, a 4" turbo direct pipe will not fit.

when I was running a big s400 single, i had an ATS 4" downpipe. It barely fits, we actually had to dent it to fit around the upipe. So there is No way a 5" pipe will fit unless you smach the hell out of it.

yea when i put my 5" turbo back kit on i noticed that there wasnt a whole lot of room but didnt know it there was anyone that found a way to make one fit...i met a guy with LLY or LBZ that had a custom 5" front pipe dont know where he got it but said it was a bitch to get in.
