Barmats,
Fulsac is a good way to go! Go with the x pipe & 2" baffle cores. They aren't hard to install. Just take your time grinding the welds off. You can install the 2" bafffles with leaving the cat head pipe on & not have to retune the bike. If you don't take the cat head pipe off you wont get rid of the heat. I had the SERT installed & dynoed at time of purchased, hoping to get rid of the heat. No luck! Too hot in Florida in march, so I went with X-pipe & 2" baffles. Yes I had to have it dynoed again. It was an expensive way to go. Oh well! It's done now. You have already paid for the Sert, you might as well use it as to buying a master tuner from Fulsac. My 2nd dyno cost me $140. It really unleashed alot of power. Original dyno was 83.53hp @ 102.8tq. After the Fulsac head pipe & baffles 87.65hp @107.40. I am happy with the way my bike runs & sounds now! Florida in August is hot,but now I can ride without burning my right leg off. If you have any questions about the Fulsac exhaust you can call Steve @ Fulsac. he will gladly talk to you. He knows what it takes to make your bike run! Fulsac also will give you a 10% discount for being a CVO Forum member.
Just my 2 cents!
