ss exchangers sound different?
I just spent the day putting used stainless steel heat exchangers on. When someone has been there before you, and used ordinary steel nuts to hold the old exchangers onto the studs, they don't come off easy!
Anyway, the ss ones are on, and the sound is now completely different! Going into a Bursch exhaust, the sound is now louder and much more tinny. Like a VW bug. There are no leaks, I triple checked.
Is this normal?
