Ho-lee shit. Cold start growling is earthquake-esque and freeway drone is like street construction work outside your window.

Macht schnell makes a product that I bought from tom at eas that lets you open and close the valves with a click of the button that is on turn signal above auto high beem. No need to do exhaust mod 
Quiet when you want and loud when you want it's awesome.

Price and install ease?
