My truck has gone from some meek, muffled 5.3L 99 GMC Sierra to "holy cow can you believe the sound of that thing!" Nice...NICE rumble on cold crank and smooth on idle. Exactly what you want. Inside, the high RPM, low gear tone can get defening for a SHORT time. Under power...hoo boy...nice baby. Cruising speeds, hardly notice it at all and that's what I was looking for. Big bang in town, nice and sweet on the highway. Get this system.
