Graves Motorsports will have headers available in a few weeks to replace the stock one!

It's called drive pressure. Yes, if it leaks on the exhaust side,you will lose boost. Now in that case of the Graves style header. Once it's up to temp, the collector is sealed good. Now would I run that header on a Boosted application? No. I like smaller primaries without steps for uping the drive pressure. I think what mad man has should work pretty good.

ive learned years ago when doing product development,making changes to a design without a good baseline is pointless.it looks cool & makes sense in theory,but if your not posting before,& after results off a dyno with a stock baseline.you could be leading people down the wrong path.
