I've found a used IDS2 off a 05 DR650. The owner says the number on it is027-2255. The websight shows an application # of 611-5653 for the 00 and the 05 DR650. He say's there are no other numbers on the exhaust, so I don't know if it is a different model modified or what. Does the 027-2255 number cross to another application? Will it work on the 00 DR650?
