Message Ok so i bought new megan racing headers for my 95 na Z and had a shop install them today. after the installation the mechanic tells me i need a longer o2 bung sensor and that apparently i need a new valve drilled in for the egr otherwise my catalytic converter and a host of other things will go to crap because it will run too rich and run poorly around town and at heigh elevations. Is an egr valve entirely necessary or is this bs? thanks
