All this talk is literally exhausting (LOL)! Now you guys have got me thinking of purchasing an Eisenmann system for my X5 4.6is.... The question is, what to do with my stock 4.6is exhaust? What is it worth and is anyone interested?

For $2400. that exhaust better do more than make sound for you.
You can go to a reputable exhaust shop (in NJ MaxPSI) and they can fab one up for less than a 1,000. Then it will be custom and one of a kind. None of that mandrel bent crap from meineke. Don't get me wrong the piece is very nice but the price is just ridiculous. Like the e46 m3. A muffler, a MUFFLER is 1700. then you still have headers, section 1, section2. A full SS from headers back can cost you $6000 I have ebay headers (SS Rep with 35k hard miles) and a bimmerworld exhaust from section 1 back and it was $1150 for everything. It is just metal and I don't understand how people just burn money away with this stuff

M3 Eisenmann Dyno
Here's an M3 Eisenmann Dyno... Can't find one for an X5...
The numbers achieved were very impressive indeed: the M3, equipped with the factory exhaust system, achieved 351 wheel horsepower, a very realistic number when considering the car's 400 crank horsepower rating, and the repeated runs that corroborated this number. This M3, when tested with the Eisenmann system only an hour and a half later, produced 364hp at peak- a 13hp gain! Even more interestingly, 100rpm earlier, at 7900 RPM, the Eisenmann system produced 363hp, while the factory system only allowed the car to produce 348hp- a 15hp gain!

That's great but I don't see an X5. You are comparing apples to oranges. Every car is different. I'd like to see real world numbers from an X5. Cause I can show you dyno graphs of an E46 showing 359 whp with an exhaust and tune but that means absolutely nothing in regards to an X5 muffler.
