It was loud and obnoxious as hell, which was really cool when I was 18. A few years on, it got old pulling into my place of work sounding like a teenager every-day, in all 4 of my V8 powered vehicles. It is nice to have one stealth vehicle.I have a 2004 sierra 1500 RCSB with a 4.8. My old man built it first. The original exhaust we put on was Kooks stainless long tubes, Kooks high-flow catted 3 inch y-pipe, and then a Pypes Violator 3 inch single in, 2.5 inch dual out cat back. Exit out under the bumper. The Pypes kit never fit quite right, and eventually a baffle in the muffler broke a weld. If you have never experienced this, I hope you never do. Quite possibly the most annoying sound resonating through a vehicle. I used the Pypes tubing back to the muffler, installed a Thrush chambered muffler and dumped it in front of the axle. This produced probably my favorite exhaust note of all time. Extremely throaty and aggressive. But, in a daily driver, I got tired of it after college. I drove between Spokane and Seattle often with this setup. It sounded down-right awesome pulling the passes at 3k RPM. My favorite section of I-90 is Westbound up and out of the Columbia River Gorge at Vantage (a windy, 4-lane uphill pull seldom patrolled by the troopers). By the top of the grade your ears were ringing. You couldn't have a conversation with your passenger, and you couldn't drown that tone out with the stereo. The drone at highway speed in overdrive was also enough to give you a headache. Like I said, it got tired of it as I got older. When I had the 4l60 built, the trans shop damaged the rusty (at that point) thrush muffler. I ordered up a Walker OE muffler of some sort (I think it is for a 4.3 astro van) to replaced the thrush. It is a 3" in, single 2.5 out, so definitely more of a restriction. It is way better as a daily now. I have since named it "The mail truck"... The long tubes with the walker give it a unique sound. Under hard acceleration it sounds like a slightly more pissed off UPS truck.</blockquote>
