looks good dude! I almost did the same type of header on my drivers side, but was concerned with not being ablt to change plugs with out dropping the downpipe. how does yours look?

Thanks again 
When I built the headers, plug/wire access was a big consideration.
All the plugs are very easy to get too. Both sides are easiest from the top, but the drivers side plugs could be changed from the bottom without removing anything.
The closest thing on the whole system is the rack/steering shaft. I only have about 1/8in clearance around my downpipe in that area, and it's 'ovalized' a bit.
Jordon- have you got your car on the dyno yet? What do you think of the setup so far in terms of fun/driveability etc ?
I'm a bit worried about turbo lag. Innovative said I won't see full boost till around 4-4500.

man its fun as hell tried to dyno it, but had some problems.. figured it out tho(leaks in vacuum lines).
nothing like 500+rwtq @ 2800. I make 14psi by 3k.
what turbo do you have? Gt80?

Fun as hell sounds good to me 
You were having boost control problems on the dyno?
My turbo is a GT80BB, R-trim, 1.32ar.
What are you running for total ignition timing? I'm thinking around 26 total will be good for around 15lbs of boost and 100 octane. I don't want to retard the timing too much because I don't know how much heat my mild steel headers can take.

Is yoru exhaust housing 1.32ar??? If so, I can understand why your turbo will lag so much. That is HUGE! Mine is .96 and Ive even got 406ci. I can tell a little lag in mine but launching it off the brakek will make up for it.
