Hello! I am a brand new member to the forums.

Question: I am about to buy a Novarossi .21 engine for my Losi 1/8 2.0. I currently have the RTR 350 engine, manifold, and tuned pipe. I am wondering if I should also purchase the manifold and tuned pipe that Nova recommends or will my current manifold and pipe work? Would I even notice a difference? They all look the same to me.
