Just had the Ravin' Z55 system put on today...I have to say I'm very happy. Anyone worrying about 'harmonic' drone in cab with this muffler, you do NOT have to worry. I think it fits the style of truck nicely - completely quiet at cruising, slight rumble at idel, nice and deep with throttle.

At first when I left I was disappointed cuz I couldn't hear it in the cab, but when I got home, I opened up my door and mashed on it a couple times....oh yeah, it sounds good.

I really like the Ravin' VP1311 tips too. I only wish they were longer like the 3" slashcuts...but they look good.

When I went to Midas to check on a performance exhaust system, the mgr told me that the Ravin Z-55 would be too loud (3" SI/SO, exiting in the stock location). He tried to talk me into a Rhino muffler (lifetime warranty), with Ravin pipes. From what I've read on this board so far, the Ravin Z-55 in exactly what I'm looking for. Did you notice an improvement in performance or MPG?
