This kit includes all you need to install a 5 in downpipe on to a Cummins ISX with a single T6 turbo (non-vgt). Like for a Signature 600 ISX or a modified Cummins ISX. The kit eliminates the need for welding as all the pieces clamp together and all the clamps are included in the kit. The kit includes a 5in 90 degree downpipe with a turbo flange, which connect with clamps and the piece of flex pipe (included in the kit) to the second L shaped piece, which has a slight bend in it to go around the frame rail of you Peterbilt 379/389 to seamlessly fit. With out a change in diameter in the pipe the 5in pipe is able to easily and quickly get all the exhaust gases out of the motor.
