Thinking about putting a barker dual exhaust on my grizz, crazy sound, saw a 550 just recently and that sounded beastly so I can imagine what it would be like on a grizz 700, os there anything else I should have when installing a barker dual, can it be ran with out any other mods? And from anyone who has this system was it worth it in regards to power? As I know it sounds mean!

Thanks !!!
