It will suffice
M4 did a decent job with this link pipe. It fits into the stock mounting locations perfectly, but does run a little close to the oil pan on the left side. I just got my R1 dyno tuned with this link pipe and a Graves slip on. The bike put down 180 to the rear wheel and is extremely loud. Not the best pipe on the market, but its a significant improvement on the stock system and great bang for the buck.
