I just called a local exuast shop today for some pricing. I asked for new shorty headers hooked up to a true duel system with magnaflow mufflers, and then continue it on out the back.
He said he could do all this for about $650. Is this a decent price? How much power would i gain from this?
(bone stock 4.6)
Thanks

 

any ideas? (are shorty headers worth the money?)

 

It'll add about 30-40 horsepower in a real world situation, Even though the manufacturer says more. Headers are worth it. I wan to get them for mine
1998 F150, 4.6L, 4x4 ORP, 3" body, 315/75R16 BFG A/T

 

well damn, i didn't think they'd add even that much power! Awesome!

 

I'm thinking about half of that on a stocker and only if it's designed right.
