also figure in shipping with jegs and summit. a year ago I bought a 2" 31.5" long thrush magnum glasspack, through summit, at the time they were 17.95, free shipping but 8 bucks handaling, it was still a little cheaper than advanced auto being 25+tax but now summit changed the price to 19.95, which would make it a few bucks more, so I bought the Thrush magnum for my falcon, right at advanced auto, and they carry or can get anything that summit or jegs gets except summit or jegs brand stuff.
