Cali Emission Truck Owners!!!!

This downpipe will fit both Cali and Federal emission trucks. If you're unsure on your model, order this downpipe. On 1 truck we had to drill a hole out bigger, and on others, it seemed to fit perfect. Includes gasket for both models as well. Works great behind my Fleece turbo.

dont buy if you have CA lb7

I have a California 2004 lb7 and i bought this hoping the install would be fairly easy. Turns out this piece is not meant for CA trucks with exhaust recirculation so i had to modify the downpipe by cutting and sanding until it cleared the recirculation pipe. then, one hole refused to line up so i had to make the hole bigger with a die grinder.

This product is great turbo used to start spooling around 1900 now it's about 1250. Egt's dropped tremendously and the turbo is much more pronounced. Excellent product everyone who has a duramax should have one.

egts drop fast, turbo spools faster, quicker acceleration(seat of the pants), little rough on install, found if you remove bracket on back of pass. head pipe drops right in.
