For that price, I'll make one of my own. Have plenty of sheet steel in the garage I can use.
I want to get rid of mine not for power or anything (both EGR and air system are gone from my Trans Am, due to long tubes and LS6 intake swap, but other than a code and no air valve tap, I didn't gain anything from it), but to see if the engine will run a bit better without it on. A new EGR valve is about $45 from Advanced Auto, and if I put it on and the truck doesn't run any better, I can't return the part.
