You arent going to see much torque just from the installation of an RBC only. The advantage of the RBC with its shorter and fatter runners is the torque curve shifting to the right and not falling off as soon as the other OE manifolds.Thanks Guys,
I'm really looking for more torque more so than HP. I think the RBC would help in this respect. I think there are kits that offer everyone you need to install.
Is this a very difficult install?
