I'm in the same boat w/ an o8Z. Headers are a waste on the c6Z the stock manifolds are that good. Some guys only gained 5HP! Depends on your goals I'm looking for just alittle more . I saw some good #s from a Killer Bee air intake, 160 degree t stat, and a tune. That's my next step after Christmas!! Good luck Jim
Hey ya jim i realy dident want to get in to the bolt on deal it starts out cheap before you know it you spend 3-4 grand could have some boost for a litle more.
