Did someone mention guns? Would that be a handgun or rifle?
I was forced into buying a new Springfield M1A National Match.I was surfing the net and found a dealer that actually had some.They seem to be rare in Canada,well lots of cheap Chinese made ones around. I prefer the real McCoy myself![/QUOTE]
I have a .50 AE on order (actually - a .44 mag that I have to convert to .50 because CA sucks), so, eventually - I'll do both :D

Not true from my experience.......the boost level won't change, but lower end torque suffers a tad with headers. They will help mid to high rpm though, assuming you are flowing more air through a CAI and ported intake and a matched tune to optimize those (btw....a ported intake is not essential with headers, just adds more air flow if done properly). Motors are just an air pump.
I put 1-7/8th Kooks stepped coated headers on my Magnum SRT8 with a 426 AFTER I put a 2.3L Magnuson supercharger on, and measured no boost level loss at any RPM on many dyno pulls. To compensate for the mild lower rpm torque loss, I change the torque converter to a 3000 stall and that combo is great!
I could be wrong with the LSA boosted motor, but it wouldn't make sense if boost pressures dropped.

It seems to me, in many cases, boost drops because it is more a measure of restriction. What is more important than actual boost is the volume of air you can push. If you can flow more volume at lower boost, you'll heat the air less (because physics and chemistry says that when you pressurize something, it heats up), which is, obviously, desirable. It could be your SRT8 just has a good exhaust already. I would've thought that little elephant had pretty restrictive manifolds (though - aren'y they multi-piece?), but maybe not as much as I assumed. That sounds like a cool combination!!!
I read a CTS-V header review in
GMHTP several issues ago, and I
think they reported a couple psi loss; not surprising...
BUT... we have different manifolds and exhaust on ZL1 so it'll be a little different but probably not too much. What's
MORE interesting is the latest issue where ADM installed a Stage 1 kit with an upper pulley, some intake goodies, isolator, ported snout, and tune, and picked up something like +60RWHP. Where the interesting facts were, were a new snout (the 'V was a new '12 model) with an additional vacuum port; but the car put down 520 RWHP on a dyno' that, in the past, 'Vs put down about 490... They suggested, perhaps, there were some more changes for LSA the '12 MY that weren't announced. Anyways - I'm just saying it'll be interesting to see how ZL1 responds to all these mods' :D
