Has anyone removed the cat and kept the stock exhaust? I would like to know if it is still just as quiet without it. I want it to breath, but I want it to stay just as quiet as it is. I must be getting old. And my Wife wants it to stay quiet also! Maybe shes the one getting old! Sorry I have to run Guy's. YES DEAR I"m COMMING!

Yeah the truck is still quiet without the cat. My truck does not have the On Star. Like you said that is big brother, and I would never buy a vehicle with such garbage in it.

Don't say that to loud. The OBDIII vehicles will have it built inOriginally Posted by David Proske

I heard some where that OnStar was the test bed for OBDIII.
You guys with the Diablo, can't you just unplug the EGR, or do you have to block it?

Not for the LBZ, just the LLY, LB7 Diablos did that.
They are sending me new a code blocker to try out though with my LBZ
In the meantime I bought the Edge Evolution and will compare the 2.
My mileage has gone down with no explanation except the Diablo upgrade. I can see the Turbo pressure has gone up some but I drive easy!
Still need to put the MH pan on but haven't bought any fluid yet, plus I have transgo jr kit to do at the same time!
