@Robert M posted:To me I did detect an exhaust leak and possibly some valve noise but I'm no expert. I'd make sure the whole system is leak free from the J-tubes on down and adjust the valves to make sure the lash is set properly. If none of that works then it may need a new exhaust.
The Tri-Mil Exhaust came stock on almost all of the cars built by VS on their stock size engines. They are very quiet and not a lot of money.
Thanks, at this point I'll take whatever option is quietest just to not take chances. I know this isn't the kind of thing people just readily know, unless we "taste tested" a "flight" of mufflers side by side under the same conditions. Eg, in various prior threads where people have sought out the quietest exhaust system, I've had trouble confidently sussing out which is the quietest.
But any inkling which is quietest? The Tri-Mil versus the Dansk that @Gordon Nichols posted (Gordon I meant to answer mine's a 1641cc). Both look like good options. Or any others?
