I have aquired a OPS .40 Monza, I have not had any luck comming up with a header and or muffler for it. It has a round exhaust manifold app .75 inches Dia. must use a spring type clamp as there is no bolt holes for attachment. I found something close for a boat but it was 180 degree turn.
Any suggestions or recomendations?

MACSPRO.com, I assume this is a rear exhaust OPS 40 then try MACSPRO.com for headers for either rear exhaust or side exhaust OPS 40's

Thanks Rudy,
It is a side exhaust. I will check them out
