Interesting..... so more or less getting rid of your cat got rid of the drone. Did that drone you had with the HKS set up also cause the plastic in your door panels and stuff to rattle?
Oh ok so just within the exhaust itself, not the hangers. I figured that's how you did it. Most people that I see with the HKS exhaust have it hanging super low like that and it looks so bad.
I think the easiest and most cost effective way would be to open up the wheel and extend the wiring from the paddle you can't reach over to the other side with a custom button mounted somewhere you can press with your thumb.
Please search next time before making a thread. There are a bunch of threads on this already.
With that said, are you talking about actual snow tires? If so, you're better off getting a cheap set of 18's and throwing a narrower set of tires on them that have some sidewall. There aren't many...
