Default egr delete with longtubes?

hey guys, im looking to go with longtubes now since I need to do plugs and wires anyway. I was looking at the race headers (non air and egr), was just wondering if it will make the car run like **** without the egr valve? its a 94 so its obd1.

You'll need to get the EGR block off plates that go on the back of the intake. Probably have a check engine light if you don't have it tuned out of the computer.

i got the block off plates, i only installed the one for the back of the intake i left the physical egr on. it just dosent do anything because i tuned it out as well. no vacuum leaks, its just a pain in the *** to reach back there

It won't run any different without the EGR but the headers and no tune will make it run rich. Find a bolt on tune without emissions and load it yourself or have a tuner make one for you.
