I’ve been fiddling with my DB9 trying out several ‘Bolt On’ performance improvements.  One of them is a ‘Secondary Catalytic Converter Delete Kit’ (SCDK) which promises to:

  • Reduce weight (it does by about 8 pounds)
  • Increase Power (yet to be seen- Dyno test coming soon)
  • Improve the Sound

This article is all about the sound, and how it changes. Continue reading “Exhaust Sound Change after Installing a Secondary CAT Delete Kit in an Aston Martin DB9” →
