It was a Dorman kit, but the first kit was defective so I had too get a second kit. I had thought about the header wrap but I didn't wrap them because it's not a performance vehicle like my mustang. I haven't had a chance too see what boost I get since I don't have a gauge mounted, but I do have the Torque Pro app on my tablet, so I will see what that say's, but I can tell just from driving now for a couple of day's, she has a lot of pep now:grin2:
