I have been looking at these now for a few days and seems like most people like these headers. Im still open to suggestions though. Anyways, I was looking to see how much work it takes to put a set of these in when I already have a Magnaflow O/R X-pipe installed. I am just guessing but it looks to me that the x will have to be cut some to make room for the LT's. Is this true? And has anyone found a set of these for under $500??
