I have taken all of my track cars with loud exhausts to the cheapest smoggers. (Imagine that...

) Express smog and GK smog, both of which publish coupons all the time. ($18,95, $20 respectively)
The young guy at Express smog at Pekham is nice and is happy to BS about cars while doing the test which I find helps. (He has an '98 A4 1.8T as I recall)
Since yours is <'95, I assume you are not OBD2, so you get the tailpipe test. It will pass that, right? You have a CAT?
