Hey guys, I bought a new 2011 zx14 back in January after I finally recovered from my R1 dumping me. 2700 miles later I start itching for a new exhaust and instead of buying the usual slip on, I really want to spend some money on Sharonda and get the full package. I love the duel exhaust, and come to find out that Brocks is the only manufacture of a full system like that; its expensive, but me like-y-lots. Does anyone have experience with this system? My maintenance experience on sport bikes is limited; is it easy enough to "do it yourself"? Does a full system create problems with the engine and require a tuning? There is also a Power Commander 5 on the website which I know very little about but seems pretty legit. Is it required for the exhaust to function at its max? Do Power Commanders need professional's to operate? Any help will be appreciated; I would like to make the most informed decision possible considering how much money it all costs. Thanks again for the advise.
