Hey yall, I wanted to share out my latest change to the G87. It's an easy DIY and makes a very significant change in the exhaust tone of the car.
The install isn't hard with a few simple tools and something you can easily DIY.
I will have a comparison up next week, but the difference is significant. I appreciate that efficient mode or flaps closed is still mellow, for early mornings or neighbors. Sport mode flaps open, especially with the Dahler controller for full open is aggressive and deeper.
This is still with stock downpipes and back box at this stage, though likely changing in the future.
Check it out!
