Damn right! Header wrap will keep the underhood temps even lower.

Farkin' eh!

Absolutely. Run duals w/glasspacks on mine and I turn my radio OFF so I can hear my exhaust!

I was thinking the same thing. Headers rule.

Not this one..............thanks for saving me the time bud........took the words right outta my mouth.
