I finally got around to having the emissions done on my '93 SS this Saturday. I was a little woried about the full CES TBE (cated) exhaust as we have fairly tight standards here in the extended Denver metro area.

But anyhow, I turned the MBC down so boost was being controlled by the wastegate pressure (~6-7psi here it seams) and got it nice and warm before test with a hwy cruise

Here are the results:

HC - - .1813 / 2.5
CO - - 3.21 / 20
NOx - - .49 / 6

(that's my reading / allowable in GPM)

Not bad!

I then proceeded to turn the boost back up to 13psi (where I bet it would still pass!) and put her away for the night ... then this morning I had a nice run with a stock S4 Avant on the way to a day of snowboarding in the beautiful CO sunshine - - I was actually Very suprised to find that he Could Not Shake Me on blasts from 60-95mph (and yes, he was "trying")

anyhow - the CES system obviously has a "real" cat!

later,
Chad

Mine passed with a 0 reading across the scale. Makes me wonder if they even had the deelie in the muffler.

Is that where you were going Saturday morning when I saw you on Arapahoe? I was coming from picking up the last few engine swap parts from Flatirons. The hybrid is running as of 9pm last night. We are dealing with the fuel and clutch tonight. Drop by if you want...
