is an 85 and 86 ATC 250R stock pipe the same?

Hey guys

Forgive me if this is buried somewhere, I spent about 20 mins searching. I need a stocker for my ATC 250R, it makes way too much noise for buzzing around on my trails. I found a nice one, but I don't know if the 85/86 are the same. I think they probably are, was wondering if someone could confirm.

Thanks

There's a slight difference or 2, but nothing that would keep one year from bolting up to the other.

Thanks Red!
