Well i got my UPR x-pipe in and it came with 4 bolts. the question is do these bolts replace to bolt to the header or the bolts to the catback? Also what else do i keep for the stock parts to use with the new pipe?
If I can recall, it's a 2-piece, so 2 bolts go to those flanges, and the other two are extras. I actually bent one of my bolts trying to install my pipe. But I have an 03, so if yours is a 0ne piece, then I would assume the bolts are for the header flanges.
first off, your not going to like the rattling sound from an x pipe and flows. is sounds like pennies in a coffie can. but back to your question, they connect your catback to the midpipe, the ones in the header are studs and you dont want to remove them unless you damage the threads. good luck and if you hate the sound, trade it for an off road H.
Yes, that'd be right. I have the UPR X Pipe with Flows, and I love it. Almost sounds like you have turbos in your mufflers. As for the pennies in a can, I've never experienced that. And I meant the header flanges, not the header studs. You have to take the header flange bolts off in order to put the new pipe in, and most likely the starter. I know I had to.
