Back from the exhaust shop!!!
Decided on Hooker LTs, no cats, stock resonator, & stock LT1 mufflers. Sounds great, quiet @ cruise but roars to life @ WOT. I also deleted the AIR/EGR and am happy to report no DTCs. For the AIR I removed the plumbing and pulled the 25 amp fuse @ the air pump. For the EGR I removed the plumbing, replaced the valve with a LT4 block-off plate from GM, and plugged the vacum source. On a side note I had a header to motor mount clearance problem on the passenger side. Nothing a pry bar couldn't take care of though.

On the highway at a steady rpm, you'll probably get an EGR DTC. With the EGR system intact and high flow cats, I occasionally get an EGR DTC. One of these days when I'm not sooo lazy, I'll program out the code.

I'll reprogram once the Hotcam Kit goes in.
