I have a totally bone stock '15 brz with the only mod being the Jackson kit. The volume level is just like stock out the tailpipe but the engine is noisier. Sounds like I have a big hair dryer under the hood. Nothing that would startle another driver, and barely any of that whine the old roots-style blowers had. Stealthy...
