3-piece Manifold
I was just wondering if it is worth the money to buy an after market 3-piece manifold to replace the stock one. I have heard when upping the horsepower they are bad to crack. Everything in my sig is whats done to the truck, but about to put water\meth kit on. Any advice would be greatly appreciated, Thanks

Just port the stocker and use that $300 you saved on something nice... The 3 piece manifolds are nice but they aren't ported or anything and they are just as prone to cracking as the stock manifold is. The only reason I see why you would get one is that your stock manifold is cracked. That's all just my opinion...
