Bought the Thermal RD Dual exhaust and here is my honest appraisal of the exhaust. I removed a Welter Dual exhaust for this exhaust. Unless you are getting on the gas you don't really hear it and not much different than the stock exhaust. My comparison is the loudest a Thermal will be. I was told the Thermal on my sling is actually louder than the way they normally intended because mine is a CAT delete. If you don't want to hear my description, of the install, but I highly recommend due to install requirements jump to around the 3:30 minute mark. When you listen to me driving it sounds like the wind drowns out the exhaust and it actually doesn't it is just that quite.
