So the drone does not occur in Tour mode, just with valves open? Is it a 100% you would recommend mod?
No.. with valves closed, almost all the exhaust note disappears. Here are a few crappy vids from my iPhone. The mic on the iPhone clipped when with the cold start because it was so loud. But you'll here me flipping between Tour and open. The iPhone just can't capture the sound correctly and looses top end sound as well as low end.
Observations so far...
- Gears 1-3, open valves, 1K-5K RPMs, absolutely nuts, burbles sounds like machine gun fire.
- Gears 4-6, open valves, tamer under 4K RPMs, above 4K its screaming again. Machines gun fire not AS intense.
- Valves closed. Sounds like standard CT5, seriously. Car disappears.
- Important Note: The mufflers hang lower then stock, no matter how high I attempted to secure them. I was reminded of this today when backing into a parking spot and hear the o'so dreadful scrapping of the muffler onto the cement parking block.. Pro tip, when backing in, stop before the block passes the bumper line in the camera... Now I have a nice dent/scraps on the inside left and right mufflers. (f me)
I have zero regrets. I still need to adjust the tips in a bit and get them aligned better but I'm smoked from the install. This exhaust is night and day different then the stock. No exaggeration.
