I have tried several exhaust systems and the one now runs about 100 decibels. A bit loud but can’t get heater hoses around them. It is a daily driver in Arizona and winters gets cold.
I can go back to the basics stock Volkswagon exhaust system but I want something a little different. Our car club which has 50 retired mechanics at least the most said that I have to cut the sheet metal to get it the heater hosing to the heat exchangers.
That’s more work than I want to do and I want a little quieter one that runs around 80 dB
I have a Four tip exhaust system that I got from Jbugg
