25/225, PF condenser will not change your situation. Muffler just deadends the pumping sound. Over the years, with long belt runs. I installed a backside idler. It stops the belt flap and, in many cases, gets a better wrap on the pulley.

Thank you for the clarification on the muffler and PF condenser.
Can you suggest where to go to find an idler for my application ?
The other numbers on the compressor are: CNKJ08 and 10979627.

Most likely will need to fabricate some mounting hardware. Maybe a hot rod site has one for your specific app.
