Just looking at exhaust options and I am wondering if I go with JBA shorties (I already know the advantage to long tubes, I've read the forum enough!) matched up with a prochamber will I be making as much or close to as much as long tubes with a regular h or x pipe? I know the prochamber made great power on the 5.0 cars but haven't heard how much they are helping on our cars. If I can't go with long tubes would I be just as far ahead to keep the stock manifolds and just buy a prochamber? Thanks for the help.
