Im looking at UDP's for my 99 cobra and keep reading that they came with a factory UDP. I know their not as good as aftermarket, but is it worth the 150 for a new set? about how much gain is really seen?
imo its not really worth it. plus if youre plannin on revving to redline, the stock damper is safest. theres more info in the new edge faq sticky if someone with better expertise doesnt chime in
