My Ride: Blah blahblah blahblah meh.
For a daily driver stick with stock exhaust for a weekend car get RPI exhaust. The constant drone was too much for me so I added an extra tube muffler before RPI exhaust. Although cabin is quiter I still hear drone at around 2k rpm. Dyno tests also proved that I lost all the horsepower that I gained before adding the tube muffler. So now I'm experimenting with other ways to reduce drone. gl
