1. Full exhaust
I would say 4 out of 5 for installation. I had a blast installing it. Learned more about my bike about taking all the plastic off. But while doing the exhaust. I removed the evap system, installed block off plates and remove the valve, did the air filter and velocity stacks, installed a camera system and also installed the woolich racing system with live O2 sensor for tuning. So I did Al lot more but took my time and enjoyed it a lot. No going to the tunner on Saturday to get everything dialed in
