Vance & Hines exhaust baffle

I have a supertrapp megaphone system on a 1978 kz650 and the po removed
The baffles to make the bike unreasonably loud. I have found a replacement Vance and Hines megaphone baffle and wonder if it will fit my system. It says fits all 1.75" outlet systems but I don't know how to check if it will fit mine. Aesticly mine looks identical to the Vance and Hines megaphone system but I'm not sure. Any help would be appreciated

The Supertrap exhausts that I'm familiar with has a stacked disc baffle. It's quite unusual. A slip in baffle may or may not work.
