Default Question for today: Mods and emissions

Curious, has anyone with full upper porting, stage one cams, headers and performance exhaust been able to pass emissions ? Those owners living in states without testing don't need to comment> We know you are lucky !

I talked to somebody yesterday about a car that has headers on a car here in Ca and he was able to get the car to pass smog.I dont know how he got this done considering the headers on these cars arent smog compliant.The smog check was done on the level,not too many shops willing to lose the license for bogus smog checks.

My 415 with full porting and stage III cams passed emissions. As long as the cats are working well and properly warmed up passing shouldn't be a problem.

Marc Haibeck did one for me when he did the 415.

It may depend on the state. VA has a pretty tight requirement, my ported intake/headers car barely, and I mean barely, passes.
