[cornerstone]

Initially I bought an exhaust kit designed for C10's from Summit but took it back since it hung below the crossmember. I ended up with a builder kit in 2.5 inch diameter. The headers are from Speed Engineering and are surprisingly good quality for the cost. There are some swap headers for the Gen 5 that are over $1200. and these were 1/4 the price.

I also changed out the factory cross member that the driveshaft passes through the middle. The driveshaft angles were needing quite a bit of correction, and this cossmember raises the mounting points of the trailing arms, thereby lessening the angle correction needed to have everything in balance. The stock member was the lowest point of the trucks frame that would possibly scrape a speed bump.
