MAC headers? Okay, its time for headers. I have been looking at MAC with the offroad Y. Is anyone running them, and if so what do you think? Does anyone recommend anything else. The MACs are around $450 w/the Y. I would love to spend 1000+ on a nice stainless set, but just can't afford that right now. If anyone has any good ideas let me know.

About 4 hours for me start to finish . If the damn stock stuff wasnt rust welded on , it wouldn't have taken me that long .
MAC's are probably one of the easiest ones to install....
Makes very good power....with tune I'd say at least 20 rwhp....
Do a search on my MAC post, you'll see some coments...
As far as install goes....

Read the exhaust FAQ - MACs make as much peak power but give up 5-8rwhp under the curve to LTs on a given setup.
FWIW, I made 410rwhp/415rwtq on a Dynojet with my old heads/cam through MACs, 3" CarSound cats, LS1 intake and an unlocked Y3000.

My friend said his MACs were great and i thought he was stupid. Maybe i was wrong.
So your saying MAC's give the same peak power as long tubes but 5-8 MORE under the curve. Why would anyone buy anything else if that were the case?
Oh yea how does the y-pipe fit? Any banging or anything?
Y-pipe is great, because it's 2.5 inches. Long Tube header Y-pipes are 3 inches thick. MAC Y-pipe fits very nicely, doesn't bang, and gives a lot more clearance.
I dont' think MAC give you as much HP as LT's, but darn close.....
Certainly I'm willing to sacrifice 2-3rwhp in place of more clearance and better price.
Clearance is very important if you wanna lower your car a bit.
I'll be putting new shocks and lowering springs this weekend, so I need clearance....
I have MAC with ORY (thorugh Borla XR-1 muffler welded in place of SLP resonator) and it sounds great....
