I ended up sticking with the Fullsac system and just switched out to the 2.25 cores and removed all the packing in the cans. It sounds really good, but what I am most impressed with is the throttle response. I had a T-Max on my 2010 with Rinehart new true dual system with their performance baffle. Bike sounded mean, but even after 8,665 miles, I couldn't get it to run right, back fire, poor throttle response, in fact the guy that bought my bike from this site is probably going to switch out the entire set up. This being said, I haven't heard a better sounding exhaust, hands down the CFR is the best sounding exhaust. You may care about having the best stats on paper, but you will get frustrated if that beautiful machine your waiting for doesn't perform well and it doesn't respond the way is should. Even my buddy was shocked and impressed with the immediate throttle response and bark from the Fullsac system and the TTS. Good luck, make sure you post sound clips if you get those CFR's loaded!
