Intake is responsible for way more of the sound of the engine than most people understand. In the car you hear mostly intake noise, behind the car you hear exhaust.

 

Not exactly. Dependig on the exhaust and your cabin acoustics your exhaust can drown out the intake sound. especially at lower speeds. I recently removed my exhaust and realized how much of a sound difference my Stillen Gen3s make. With the exhaust on you didn't notice it much.

 

get motordyne art pipes. it wont throw a CEL so you should be good with warranty stuff. will make your car noticeably louder.

 

This is just as bad as drilling holes in your exhaust.
