LB7 swit h from Cali to fedral emissions

[blk smoke lb7]

Hey guys doing a head gasket job on a friends California model lb7.How hard is it to convert to federal emissions? I will be ordering a new down pipe for this truck, if I'm converting it do I still have to ask for a California down pipe? Is the bolt pattern different?

I already have the heads and y bridge and some of the small tubing to convert.Thanks in advance. Scott

Unless he is swapping the turbo for a Fed, you need a Cali DP. All bolt holes line up except one.

Missed this one, ring me back tomorrow when you can. You can get a Fed DP to work on a Cali turbo, just oblong a few holes about 1/8". It still seals fine.
