There are hundreds of companies who sell the aftermarket kits for them. Check eBay.

The GM part was for the valve block off and nothing else, anyway.

Why would someone go through the trouble of deleting the EGR valve, but not take all that **** out too?

It's all part of the emissions system. I just think it's a waste of time deleting the egr valve without taking off all of it.

IMHO, it is a waste of time deleting any of it. It's not like it's any big performance mod.

Less stuff to go bad, like vacuum lines especially. It's almost all vanity though.
