Lots of possibilities to upgrade performance, it basically comes down to your wallet and desire. Gearing, high flow muffler, professional tune and some trans work will really liven an R up. That said, as some have said earlier at ~4700lbs Rs are pretty heavy from a performance standpoint. I’m addicted to whine, and mine goes really well and is very fun to drive, but she also gives up 1500lbs to my Z06. Head to head, from a sheer performance perspective there isn’t much of a competition. From a smiles/mile, the R wins hands down.

I used to have an 05 and loved it every second. I upgraded to a FPR (final production run) that previous owner did the tuning for me. Someone mentioned something about a whine.. That would be as a supercharger. You have been given a wonderful toy.
If you want performance like this:
This is a great toy and love it every second I get behind the wheel. Even if just to start it. Yes you have some required mods for safety and some for sound and some for power. I was going to say "I love it to death" but that just don't sound too good.
Enjoy your lifetime smile!! (permagrin)
