Ill post a vid some day ;) i did, but the sound becomes annoying when traveling higher speeds. As for cat - yes, if u'd keep the stock mufler but change the cat - even stock exhaust would sound rather grunty ;)
Not anymore. It had in the first 1k km. Then OEM crashbars had made it a bit worse, but i have solved it with aluminum spacer which goes through the engine and is now super smooth. Exhaust had no influence for vibrations
