OH! muffler, that's what i thought about yesterday
1) a second turbot is a great muffler!
2) the FTE muffler/resonator is as good as the internet says. they are super easy to package, decent price, and make a huge difference. even thought the small tube spiral seams weird, it's amazing
the FTE is like 50% of the exhaust on the '55, with the tip right at the cab. you still can't hear the exhaust over the turbo and engine noises
