The X-pipes do sound pretty good though, especially with a 4.6. I remember my M5's exhaust system, it was a full Dinan and it had such a muscular sound... it would actually burble when I let off the throttle and that was just amazing. The tone of the M5 mufflers was just incredible, you could feel the exhaust from inside a building if the M5 was parked outside, it made people so uncomfortable haha

Which Magnaflow X-pipe model are people using for the X5?

I would opt for the magna flow x-pipe insert since the old 4.6is middle resonator has this incorporated in it. Helps to smooth out the pulse flow. I think two straight pipes may induce the drone and falling off in performance just a little. Like I said if you can find a set of the Dinans then leave the middle resonator on and just add the Dinan cans to the rear. I was fortunate enough last year to find a set at a boneyard that looked to be brown and rusty on the cans but since Dinan uses a thick stainless steel construction all that was needed was an afternoon of exhaust polishing and they were as good as new. It was a tiring process but for $250 at the boneyard it was a treasure to obtain knowing what they went for when offered new and of course how glorious they sound on the X5.
