[Wret]

I was on my second rattley stock muffler and was looking for something with a little more aggressive sound. These look like straight through mufflers but actually are not. They do employ some noise canceling technology. They are currently available only direct from Flowmaster by special order. Just finished installing a pair yesterday and I am very happy with the result. Barely noticeable at idle but a deep growl when accelerating and a pleasant bass burble when letting off the throttle. Noise level at cruising speed is louder than stock but no annoying drone.
