I ordered an MBRP exhaust from a vendor, and come to find out, it is on back order for a couple weeks, but he has an AFE system in stock he would sell at the same price. I havent heard a lot about AFE exhausts and was curious what you guys think. Have him ship the AFE? or wait for the MBRP? And list reasons why or why not to go with the AFE please and thank you.
