Default CR125R Exhaust Flange Interchangeability

Anyone out there know what years interchange for CR125R exhaust flanges? Last two CR125s I've touched have had cracked flanges and the '03 I have now shows the part NLA from all online vendors I've checked. I know the '02-'03 swap, but I'm wondering if other years will fit it as well. Pro Circuit makes an affordable alternative, but it's for a flip so I'm looking to get a used one.

Take a look here - Honda CR125 Bike ID. Looks like 90-99 interchange, then 00-04 are each unique, then 05-07 interchange. That said, sometimes a relatively small change that won't affect interchange causes the part number to change.

Thanks! That second bit is the info I'm looking for. I want to make sure it fits up right, even if it has different performance characteristics. I may just have to bolt it up and weld it (to prevent as much distortion as possible) and use a little high temp silicone to make up for whatever warpage the welding may cause. If that doesn't hold up, I'll have to put in an order to Pro Circuit for their. Boyesen carries one too, BUT it's like twice the price of the PC unit.

I can't imagine what would change on the exhaust flange other than maybe length, or possibly material. If you find another that is the same OD, length, etc and it bolts up I would say you're good.

I was able to weld up the original and it's holding for now. I'll let the buyer know and let them decide if to run it or replace it.
