On the way home I put it in cruise control at about 65 mph (with video) and no drone at all. I will post the vid on the gb thread when I get home tonight

This is really hard to believe because i have it with my conservative magnaflow mufflers (which have an S curve inside) and I still have drone.

After trying this and the AA exhaust i think any aftermarket exhaust will drone-6 cylinders are just loud.

i really want more opinions on the CP-E exhaust, because i don't know who to believe anymore. Active Autowerke toldme that their unit had no drone and that was total BS, the drone was so bad i had to take it off in a week.
