Well I finally finished my exhaust system. It only took a year and $1500+. It consists of the doug thorley 301y-fed tri-y headers, 2 individual magnaflow 45004 cats and a flowmaster 17165 cat back kit. All four O2's were also replaced as well. the induction noise on non-WOT has reduced a bit as a result as well instead of hear one louder exhaust pulse out the rear every revolution. they are quieter and multiple smaller ones. tri-y design at work for sure. My shift pattern seems to be effected by the change I think too but I did change the MAP and MAF sensors at the same time. Now when I punch it, I hit the rev limiter at 5500 in first and the tranny does not even begin to shift. a little off the throttle it will shift before hitting the limiter. Will have to do some PCM work.

I'm pretty sure that is how my 00 OBS CCSB is and it is all factory exhaust under it. I was going to stick with the same pipes before the muffler, add a Flowmaster 50 or 70 series dual in/out muffler with twin tail pipes in the factory location.

Here's my thrown together "y" pipe. Single 3" and 12" bullet as resonator with a turndown tacked on. Too loud, I took pics but no sound clip.

Now the truck has a Magnaflow and duals. I will update after I get pic's and a video or 2.

96 vortec 350. 93 y pipe, straight 3" no cats (what are those?), into super 40 single in single out, custom tail pipe, 4"x20" tip dumped between the hitch and leafs hidden from average persons sight. Favorite so far
