I went with the Agostinee system, 10lbs weight loss, super high quality easy instal. Looks great, sounds much better and seems like it has more punch. I kept the stock muffler and it runs like a champ, no hiccups or off throttle pops.
It is a chunk of change, however, think it was about $900! But I figured it will last as long as the rest of the bike, not sure that will be the case with Ali Express type? Also, I thought it was cool it’s made in the same town as MG! I don’t have a 23, so it’s a bit different.
