    Drove the K20 to American Muffler and had exhaust installed. The system is 3" pipe from the headers to the x-pipe, then 2 1/2" to Dynomax UltraFlo's and continues as 2 1/2" pipe dumping at the rear of the flatbed angled down slightly. The truck is running pretty rough, back firing or missing - now that I can actually hear the motor it sounds like a timing issue and a rocker or two need to be adjusted.

    Here are some pics of the system. This is the X-pipe that I had built by someone I found on E-bay.

    Rather than use the collector piece that came with the headers, American Muffler made their own piece

    The passenger side collector was fairly close to the transfer case. Here is a pic of the pipe coming over the transfer case

    Here is the X-pipe installed directly behind the transfer case

    And here is an example of the welds at the X-pipe

    Here are the Dynomax mufflers

    Pretty straight shot to the rear of the truck

    The pipes dumb right before the hitch and are well protected

    As the motor is running rough I have not gotten on the gas to see how the system sounds - will have to wait to see what is wrong with the motor.

    What is that extra crossmember you have behind the transfercase for? The one with a small skidplate on it.

    At first I thought that was where the carrier bearing is located. But looking again I think the carrier bearing is about a foot behind it. I will take a look and let you know for sure.
