I was at NJB Automotive in Westerville OH (Columbus) last week to have some minor work done on the 360. While there I got to listen to another 360 with a Novitec muffler but I'm not sure what version or even if there are different versions. Regardless, this Novitec was LOUD!
Much louder than my Tubi. It did sound good in a "lets-attract-the-police" kind of way, and was very different than a Tubi but seemed way too loud to live with on a daily basis. I'm sure it would set off car alarms and offend the neighbors. I doubt one could carry on a conversation in the cabin. It reminded me of when I had Fabspeed Supercup "mufflers" on my 993. It made the car sound like a Porsche should but it set off car alarms, produced a terrible drone right at about 2700 rpm, and made it impossible to carry on a conversation in the car. I kept them about a month before selling them.........made my neighbors happy.
I much prefer the sound and tone from my Tubi. Just my $0.02 worth
. Probably old news to most but it was the first time I'd heard a Novitec in person, and I was surprised.
