I just bought my first Ducati, its a beautiful Monster 821. I test drove the 821 and the 1200, though I chose the 821 because the sound from the exhaust sounds so much nicer than the 1200 (both stock, of course). Everyone is telling me to buy the slip-on Termignoni exhaust. I really want to, though the sound is so nice, especially when the engine idles, that I can't even imagine it sounds any nicer with the upgrade. I can't really hear the difference of sound in youtube videos. I don't care as much about performance as I do the sound. Does anyone in the great Los Angeles area have a Monster 821 with a Termignoni slip-on exhaust? I would love to hear it in-person if anyone could show me. I would really appreciate it... What happens to that beautiful idle-popping noise after you install the Termi's, does it get even louder? Any thoughts, guys? Money isn't an issue if the Termi's will make my bike sound even meaner... Any thoughts, suggestions, or comments? Is there a better/louder slip-on than the Termi's? Again, price is not a factor, I just want the nicest sounding system ever. Thanks Ducati fam!
