Ok my Clifford Intake has arrived. The "GMC" headers that I ordered arrived today. When I opened the box; inside was a paper taped to the inside lid. From "Patricks' ". If I had known they were coming from them I would have bought them directly instead of using "The Truck&car shop". What issues am I going to have with installing the headers? Paper talks about grinding in acouple of places for fitment. Also can/should I drive from my house to muffler shop or not? About 5 miles.
Thanks 4 the advice ,
