I have to say, I don't think anything is as bad as stock exhaust. But there are some people out there that was want something that looks cool or is quiet.
I have the MZMIAMIPARTS expansion chamber and it is not only cool looking but very VERY loud
Hate to here this as I was told they are not that loud. If it is too loud for me I will try a silencer. Wonder if there has been any changes made to them between yours and mine. I have not tired mine yet but only got it a few weeks ago. Thanks for the input.
