2 guys i know at the track runs that setup. There s gain on the track but barely no difference in sound. You need an aftermarket cat back to awake the PC
So the prochamber will only work with the mac LT's without any modifications? I've thought I've read other using the prochamber with like bbk or slp?
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.
