The websight shows an application # for an IDS2 exhaust for a 00 and 05 Suzuki DR650 of 611-5653. I found an IDS2 for sale that the owner says came off a 05 DR 650 but the number he found on it was 027-2255. Will this work on the 00 DR 650? He says there is no other number on it, so I'm not sure what the number he gave me represents. Any input?
