New to R3

I have a 12, but I thought all Roadsters were the same. The crossover isn't very big, in fact I was surprised how small the crossover pipe actually is. I drilled my baffles, but never could get the cat out. And yes the stock exhaust is stupid heavy.

WELCOME from sunny and HOT WA!
That crossover box is empty, however, due to its design somewhat restrictive.
If you go with TORs and 2780 trip K&Ns with a dyno (best) or canned tune, you shall be impressed with the improvement!
 
Hello Rick nd welcome from VA. beside the cat delete when using the TORs, they are a 1/2 bigger in inner diameter. I say just set your stock exhaust aside for now and slip on some TORS.
