Question New EGR???

I have a 1997 LT1 WS6 with the T-56. I just replaced my entire exhaust system with PaceSetter Mids, Random Tech. Dual-Catted High-Flow Y-Pipe, and SLP LM1 CatBack. Now that my exhaust has no back-pressure or resistance or anything, I am in need of a new EGR. Where can I get one that is for modified exhaust systems? Apparently, a new OEM one will just send out more codes again. Does anyone know? TIA!

I am going through the same thing right now but I'm failing on the emission test because I can't get the valve to open with the engine running. Hopefully someone knows the fix for this. I've search here and at CamaroZ28 and didn't come up with anything.

My valves are opening and the selenoid is working and everything like that, but the light still comes on... Originally, I thought there was just simply some carbon under the valve, but that wasn't the problem. So, I don't know whether or not I should get an EGR for specially modified exhaust, or just a regular OEM one. Does anyone know anything???

Most people just block it off,but you will have to delete it in the PCM,You will be able to pass emissions.
