Define loud.
Do you mean...
1) I canāt drive through town without giving every law enforcement officer I pass whiplash loud? I have to set up a go fund me for tickets loud?
2) Noticeable, but not obnoxious when light in the throttle. Loud enough under full throttle to turn heads. Overall quiet enough to not attract unwanted attention from those with light bars- unless you are driving like you stole it.
If you are looking for option 2 I suggest a Thermal R&D.
