Manifolds or stay with what I have?

This strikes me as funny,,,

Headers are probably the cheapest, most effective way to gain 10 - 12% horsepower..

Getting rid of headers is prob. the most expensive way to lose 10 - 12% of your horsepower,, lol go figure.....

Take your header leak to a proper shop,, they're paid to get those bolts done up, and have experience you can't imagine.. They have to work on IMPORTS..

They're cost of repair will be insignifigant compared to cost of HiPo mainifolds,, and you get to keep the H/P.. ...my .02
