On Saturday morning I completed the install of the Fullsac Stage 1 with 2.0 cores and have put over 200 km since then and all I can say is WOW! What a difference. I held out only because i really liked the stock look. Did not want to mess with the warranty , noise laws and wanted to be able to hear the radio. With over 15000 km i installed this exhaust on my ride 14000km too late...ish. It took me about 8 hours to install. Took my time and did it right. I also even painted the inside of the cans before the tips that had some surface rust. It looks much cleaner now with the 2.0 core tips sticking out. As for the radio i can hear it over the exhaust once the volume is raise more than half way. Which is where i usually have it when the amp is not cutting out...ish again. I could probably do this install now in about 3 hours now that i have done it once. The only thing that i would suggest is when it says after grinding out the welds on the baffles to tap them out......it should say give them a good whack

. Thats what held me up on the first one. The second one did not take as long when big Bertha came out to play.

. Very easy. Just in case i have held on to all the stock parts in case i need to swap it back but i do not see this ever happening because i am in love.........the power gain is awesome.....before the upgrade i was shifting from 5th to 6th at about 140 km now i am shifting at about 160 km. The bike is also shifting much better......no more hot leg. no more bogging at about 5000 rpm and the sound is perfect......sounds like a Harley especially when you open here up but it is not that obnoxious loud but crisp and clean. Wife loves it and no complaints of heat. I can go on but i am going for a ride.

For anyone just thinking about doing this upgrade......just do it thats all i can say.
Thank you Steve, Alice and Fullsac for helping me out and answering all my emails and questions.
