e test ?

[shmed]

i just got my notice to get my gn e tested, its the dyno type.
now i dont have a egr valve because of the champion irons.
but i do have a 3" cat i got from Red A. im also running 55lb inj's
and a cam from TA perf that has a lobe separation of 109 and a .465 lift and a .425 exhaust and set at 4 degrees adv.

ive also seen mention of 3 way cats, are these better? how can i tell which one i have?

any tips to get my car to drive clean?
thakns for your time.

The 3-way cat controls hc, co and NOx. Since you don't have an egr ports (with aluminum heads), you're going to rely on the cat to help you get through the NOx portion of the emissions test. So long as your engine runs well, you should pass just fine. If by chance you should fail, post all readings from the test so those that chose to help (by posting a solution) will know all the readings. Post even the readings that pass.
