Just a quick question on downpipe sizing. How big a pipe would you need for 300-400hp? I was thinking 3" would be OK and probably not cause any interference problems with what I was thinking. 3.5" could probably be made to fit though if 3" isn't big enough. The downpipe will go right down and dump out a cutout so it won't be too long. ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)

you really need a 3" if making over 500rwhp
for turbo, the bigger the better
only problem in a fbody its hard to get a big one in
what kit are you talking about?
on the QMP, and turbotech, 3" is about the biggest you can get, and thats hard to squeeze in.
ive heard of a 3" CAS (dual for twins) but it looks like it tapers to the 3"

So it seems short 3" downpipes off each turbo will be more than adequate for up to 1000hp total. Ummmmmmm......That should do it.
