Hey I just replaced the a set of 2 Chamber 40 Series Flows for the 3 Chamber Delta Flow 50 Series. The sound is still great, deep, and yes, still loud, though not as bad as the 40's

I hated the 40's in the end, good for a race car, but not for a street car that gets stuck in traffic. The 50's are still a bit too loud but most of my problem is the 3 inch Torque Tech exhaust I'm running. I added a cross over, a bit up from where the optimal (performance) place to install it was, but now have an annoying drone at at certain RPM (800 - 900 and @ 2100).

As I learned, everything impacts on other factors, best to talk to someone at a show, get there opinion.
