MAC Prochamber Worth It?

The important thing to remember is when using long tube headers, you really need a mid-pipe that is designed to go with long tubes. Remember, the stock headers are short tubes, so if you buy a mid-pipe to bolt to your stock headers, they are going to be meant in length and bolt design for short tubes. However, if you buy a set of long tubes, and try to re-use the mid-pipe that is meant for the short tubes, you will have to cut and weld them. I did this with my prochamber and long tube headers setup, and wish now that I hadn't. It's better to have parts that bolt together, and fit correctly, than having parts welded and stuck together.
