Where I autocross, and at tracks like Laguna Seca, there is a 92db limit (measured 50' off to the side), that I don't want to worry too much about going over. Would like a long distance drive to not require earplugs, too.

So, something that adds power, saves a few pounds, but isn't much louder than stock. Anything like that exist?

Thanks!
