not really. i had to adjust it a bit after fitting it for the first time. but it was no biggie. and no issues using it! i love it and it suits the bike´s character.
nope, it´s stock. i would probably do it if i could use this exhaust all the time but unfortunately here in Sweden it´s tough to get by even with the stock exhaust on track days.. but when the warranty runs out i´ll probably get a race ecu mapped by gabro.
