What kind of a difference will headers make? Do they help with top end or low end or both? Do you guys trust the Ebay headers?

 

deffinately help the high end and youll loose a tiny bit in the low end. ebay is only as good as the people using it.

 

Difinately helps mid and high end, shouldn't affect low end much, but definately won't gain any low end. If they are in good condition on bay you should be fine, but look at the history of the seller good to see if they appear to be honest.

 

In my experience, it really depends onthe year of car/truck. The old muscle cars...Well yeah, they would help with hp gains and overall performance. Chips and programming software is the way to go in today's age...Considering vehicles are being ran by computers. Anyway, I shop with Ebay frequently, and as long as you buy from the Ebay stores (such as Performance Curve), youshould be fine. I would be cautious of anything thatis not an established business. Checking the feedback of the seller is really all you can do. Good luck. ZT.
