Re: 1998 Silverado 1500 Z71 ECSB Daily
the best video i found was this one.

skip to about 2:10 in the video. this gives you a good idea, and this is with 2 1/4" pipes not 2.5 or 3"
the ultraflow is nice and deep, yet it has none of that glasspack pop and crackle that you get with the magnaflows. it has an amazing tone, i wish i would have gotten a clip of my 95' RCSB. it sounded sweet, best i've heard for a stock cam tbi 350. my setup on the RCSB had mid length headers, custom y pipe, no cats, and a 3" in out ultraflow to a single 3" tailpipe. no drone whatsoever.
