WooHoo Passed Emissions
After changing camshafts last fall I was worried about passing Missouri's emissions testing this summer. Mo. has station testing and mobile testing. If you drive by the mobile van twice in a row and your car passes, you don't have to do the station (roller/tail pipe) testing. I passed the mobile testing. 
A few mods:
Comp Cams custom grind 224/230 605/622 112
CNC Cylinder Heads ported LT1 heads
EM long tubes
Dynatech 3" PowerCats
Flowmaster Force II cat-back
AS&M 52mm TB
Impalla SS head gaskets
Tunercat tuning by ME with a little help from Tom "tjwong" Wong

congrats on passing smog van
i have an lt4 with the force 2 and recently made the group purchase on the em headers. do you have pics of youre header to catback install? im planning on loosing the converters but i would like to see youre header to force2 setup. i also see you have cnc heads with a pretty healthy cam. did you by any chance use llyod elliot for youre head and cam choice? ive talked to lloyd and he seems like he can really make an lt motor run. thanx.

My heads/cam package is from CNC Cylinder Heads in Florida.
I slip fit 3" bullet cats onto my header collectors. Then had my Force II cat-back's front pipes shortened and narrowed to fit the headers/cats. I'll try to find pics.

thanx for the reply
im also work for the uaw-local 862-and im new to the c4 forum. i greatly appreciate any feedback from experienced owners. em seems pretty proud of their collector extensions so im looking into alternative solutions to connect the force2 to the longtubes. im a novice on the tuning part so im still trying to learn as much as i can. i contacted pcmforless and they were helpful, but it seems you do youre own tuning. i have a laptop, and have looked briefly into aldl cables and software to tune myself. it seems youre mods will be similiar to mine. should i be intimidated by the tuning part?
