My vid is so quiet. It actually sounds a bit quieter than Darren's "After Install Vid" of his in person. Listen to that. Very similar sound. My hi flows are not yet on video and even then it is not obnoxious. Much louder? Hell yes, but my gf even loves it. It's a great deep sport truck tone now. Best set-up on an F-150 I have ever heard in person. Try the 12198 and see how you like it. If it is still not loud enough, you can always have cat work done, but I have a feeling it is exactly what you are looking for

 

Heres the video, begins at 2:00

I'll start a thread as soon as my sound clip is made and uploaded...
