I've got straight plug heads so I don't think that will be an issue, thanks for the idea on the part number, I hadn't thought of that and it should help me pin it down before I get crazy. Lets just hope the p/n is stamped on the headers . As far as exhaust goes I've got some reducers down to 2" and a pair of smithy glasspacks from summit, I'm planning on clamping them straight on and then when I get a chance probably after the holidays I will take it down to the muffler shop and have them run it out to the back with an x-pipe. I figure it'll be good and loud but still bearable to drive. Thanks guys!
