| " but what I meant was that my NA motor (and other NA motors, IMO) really doesn't deserve name-brand or even OEM parts. The motor doesn't know the difference. Its feelings aren't going to get hurt. Hence the eBay treatment. " that's what i don't understand, why waste the cash on a un-necessary mod for a motor when "it doesn't deserve OEM parts" as you put it. as for my headers, they are the same ones from the the first Z, that i bought back in 01. i have dyno-ed b4 and after the install of the headers with cats, wasn't much if any of a change. Afterwords, i started running test pipes on that Z and my current Z. But i never had a chance to re-dyno that Z before it got hit. never got a before dyno on this Z before i pulled and cleaned and bolted on all my old mods.
