It has a lot of drone, I can tell you that. I don't mind it personally. People always complain about drone but i'm all for it. It's for some reason one of the loudest cars i've had...and it's only a catback haha. I'll try to make a video today if I can
I just installed the solo performance center dual exhaust on my smart and I have to say I'm extremely happy with the end result and I just thought I would share a quick video (before and after) that I made with everyone here in case they are thinking of going aftermarket with Solo.
