Hey guys i have a stock 5.0 with just a k&N drop in and a flowmaster muffler with no cat. I was thinking about getting true dual exhaust for it. If so how much would that cost. I already have one flowmaster muffler 2.5 inch. So i'm guessing i would need another. And how much of a hp increase would that be?

FeatherFoot can probably give you some dyno numbers on this and I hope he recommends a Big Single System for your truck... FeatherFoot?

Well I have true duals on my 305 and I really couldn't tell you how much of a gain you would get, but I have been very happy with mine, so I so go for it. I have dual Flowmaster 40's by the way..
