changed my setup to quiet it up alittle more and it did get alittle better with this muffler over the splitflow by dynatech. Also the tail pipes helped tone it down but its still loud and mean. Nice deep tone, not as raspy or higher pitched like i thought and kinda hoped it be. I dont like alot of rasp but i wanted abit more of a higher pitched tone like a vette lsx car but oh well
Idle is tuned more in this vid to around 900 rpm +/-50ish rpm. it moves around alittle but its alot better than first startup
see my other thread about that
