single stack with twin turbo's

I take it the differences in your size of down pipes is due to the size turbo's your TT kits use?
Oh OK. Did your TT kit come with a short 5" downpipe to clear past the frame rail to where the exhaust originally connected?
if your 475 has a 1.32 a/r then they both use a 96 mm turbine , usually the tighter a/r's use smaller wheels .

Hey mainer, think it would have been possible to fit a 5" downpipe in there? It looks like it'd be tight, I'm still trying to put some plans together.
the tightest part is the turn off the turbo, it only clears my coolant bottle by about 3/4"
if you relocate or get a smaller coolant bottle its definetly possible but not really necessary to go with 5" ..... 4" will flow enough till up around 800hp i believe

I have a 7'' stack twins no muffler truck i a ec it has some rummble when accelerating but cruising it's naot bad at all. It sounds really good and you can still talk to the other people in the cab.
I've got a removable 4" turndown right off of the MPI Down pipe. It ends under the pass side door. It's not loud @ all, unless Im WOT. I made it removable for the track, so I dont smoke the lights.

How does a turn down right behind the front tires keep you from smoking the lights? Seems to me it would make it easier to smoke the lights.I've got a removable 4" turndown right off of the MPI Down pipe. It ends under the pass side door. It's not loud @ all, unless Im WOT.

Because when it's removed the smoke goes straight back, and not down. I forgot to take it off a few times, and have ET'd 9.60's. I actually got the boot one time, and had to go talk to the tower to explain there is no way possible that I pulled a 9.xx @ 110mph. The Pic is one I made for Jordan (before polish), same as mine!
