I very seriously doubt it! I don't ever recall any of the current stang owners raving how their stock manifolds gave them an increase in horsepower, but I may be wrong. If so, I apologize to the rest of the members in this forum.

 

Appreciate the info guys,now I know the difference. I'm with most of ya'll, Ithink that I will go with the lt headers. They seem like they would free up more horses.

 

long tubes! i have shorties and they didnt do a damn thing for me...get the long tubes...bbk slp or mac

 

When you guys got the long tubes, what did you have to change as far as the mid pipe and cats, or did you just have to redo the whole exhaust?

 

When you get you LT's, get an o/r mid pipe H or X whatever floats your boat.
