Yesterday I installed a set of Speed Engineering's long tubes and I would suggest contacting them about their product. I used their Xpipe kit and for $179.00 I highly recommend it and their headers.
I think in any set of headers, to bolt to the existing system you are going to have to have a reducer of some sort to go from the 3" OD coming out of the headers into the factory size. I went Speed Engineering all the way back to the axle back and the difference between the two was about 1/2 inch difference.

If you’re adding headers, it would be best to go ahead and include the xpipe that’s required for that particular headers. They usually bolt right up to any axle back exhaust system.GL
