Mediocre Sound and Quality

I didn't want something too loud because I'm a good neighbor. I settled on this 50 series as it seemed to be very balanced. Unfortunately, after install, I realized it was much tamer than I was hoping for. It's got a decent idle rumble but the exhaust note really fades after 2,000 RPM. I'd sum it up as a stock 60's F100 sound. It's whisper quiet at cruising speeds. No joy in stabbing the throttle. Also, the clamps for this kit are junk. Now I have to get it welded! Stick w/ a 40 or 44 series.

good sounds
