The Milltek increases your exterior volume and bass rumble while keeping the cabin quiet. Even after hearing the latest exhaust offerings, I still would choose Milltek....I love how quiet the car is when I am cruising, but when I am driving with the windows down, the sound is not that what I had hoped. Do you find your aftermarket exhausts increasing the volume in the interior, or did just add rumble that is noticed when outside the car? Thanks.
When I had a 4cyl car back in the day I put a stillen on it and regretted it forever. It was so loud, it made long highway drives painful. I am hoping it is not the case with this car.
