I ordered Jet Hot Long Tubes from MASC Performance. They e-mailed me to let me know what was going on with the shippment multiple times. I also called them just to see exactly when I could expect my headers to be shipped. They called Jet Hot for me and found out the tracking number, and then looked up the number for me and told me what day it should be at my door. I know this stuff is expected of companies but not many follow through with this level of customer service.

So A+ for MASC, for anyone thinking of ordering from them.
