Here is out new design. Works on an FC or FB with a 13BT, 13BREW, or 13BRE. Slightly modified unit works on the FD too. Things changed from past standarized unis are the use of 321SS instead of 304SS, smoother bends, smaller runners( aimed more at most street guys) collected flange for better overall power, and closer waste-gate placement for better boost control. If I can find some time to work on my co-worker's engine with him we're going to try and do some dyno comparisons. Won't be for a long time though...











For those that didn't see I've also got a shorty system for the FC/FBs, don't plan on making a shorty unit for the FD chassis..

Looks good E....



When do we see an "in the car" picture - I'm curious how close it runs to the shock tower and how much room that leaves for intake plumbing, etc.

Not in my experience, I do however think I know why other companies long runner manifolds work better than their shorties, nothing to do with length at all.

Looks good, but why did you decided on a collected system, vs your old uncollected?
