My Eisemann race is really loud. I like it, but long distance it can get slightly annoying, especially early in the morning.

ACM Custom Modded Exhaust is a great system. I actually came from a E Race, a Black Series to be specific with connecting pipes. The drone killed me because i couldn't have a normal conversation over the bluetooth and things just got annoying over time. Let me tell you something your not wasting your time on this ACM setup because 1 is it cheap and 2 no drone with a great tone/sound. The loudness is the same as E race but with no drone as i wanted. Price for me doesn't matter Cheap or Expensive.

EDIT: Cruising speed at 85mph in top gear is 78db. Full throttle is 85db. These are all in-cabin ratings.

Macht schnell xpipe which deletes primary and secondary cats and uuc/Corsa axel back exhaust. Outside it's tame when cruising and loud and high pitched when you punch it. Interior is almost no drone, it is an amazing sounding exhaust.
