Allrightythen, got the headers installed. Took two days to get that done, using one arm. Gonna try to get the rest of the exhaust done this week. Bought a bolt in cat, Magna flow, 1200 bucks for a "direct fit" that has an overall length of 17" to bolt up to the 12 1/2" space. Good thing the headers and cat back are needing some fab to fit.
