Thought I would circle back and complete this post as well. The Flowmaster or glass-pack sound I was getting from the first driver's side (US left-side) exhaust manifold existed because whomever I bought it from had disassembled it at the bellows for ease of shipment. I was told that this should never have been done. So, a $150 mistake on E-Bay. The second time, I bought the exhaust manifold off a 560SL being parted out and got 15mm tubing hardware (elbows and unions) to slightly re-route the EGR valve. One add-on catalytic converter at Mighty Muffler on Cave Creek Road later, and it sailed through Arizona emissions, which definitely appeared to be somewhat of a surprise to the guys working the emissions line,who first had to figure out why the 1975 VIN number and the computer did not seem to align properly. Where were the letters, they wanted to know? In 1980, I said. Thanks for all the tips and suggestions. Between everyone here, I am sure that I have saved at least $5,000 on the 75 450SL and 82 380SL since I got them in December 2011.
