Hi
I fitted a load of Volvo V8s in the early 90s and they were available with the Volvo's Transom Exhaust System, the exhaust outlet Y that bolts onto inside of the Transom Shield was removed and a blanking plate fitted, the Large Stainless tubular baffle fabrication was then installed running across the rear of the block after cutting out the Exhaust holes into the Transom and connected by 4 exhaust hoses . They did sound really good when running but I think certain Marinas had issues with the noise .
Whether they are still available is another question !!!!
I know that Looe engineering had one knocking about for some years in their Plymouth ( Mayflower Marina) shop, and they may still have it laying around the workshops somewhere !!
