With over 140 hp at the rear wheel , the only one who should see your exhaust is your riding buddy. Seriously, i would rather spend the equivalent 1300 US dollars on four trackdays and learn how to ride this missile in safer surroundings. Ive had Staintune, Remus ,luftmeister , Bills Pipes ( shortracker ) and FMF. They all had five things in common. High price, lighter weight, louder, most of the power gain at high rpm, and they run cooler. It occurred to me also that one other trait was shared. They got louder and louder as they got older. Some were re-packable but most were not. Loud pipes are annoying to me before the end of a long ride and became tiresome. YMMV When my 1190 finally arrives I plan on covering up the muffler with a set of Nomado saddlebags with the cut out . I've learned a lot from you guys. Looking forward to October . Hope its early October.
