Instructions - 818189 instructions.pdf
This exhaust kit is designed to fit 1500 and some 2500LD trucks with both left and right bank catalytic converters on the engine side of the 3-bolt flange of the down pipe. If your C/K 2500 truck has one catalytic converter on the engine side of the 3-bolt flange and one catalytic converter on the muffler side of the 3 bolt flange this kit will not work.
