I wanted to see if the BD manifolds were a good investment but I was told to get RDL manifolds and up pipes. Were can I find them and how much better are they from the BD manifolds?
Rick DLance he is a member here he also has a few vendors selling his stuff. For a bit more money you get much better flow than you would by just using the bd manifold.
Rick has dyno'd a stock truck with his up pipes on only and it was in the neighborhood of 20hp gain. Headers and up pipes help a lot more than you think and well worth the $$$
