For people that are making 350hp+:

do you have trouble passing emissions?

 

Depends?? if they don't have cat, then no... well very few..

 

as long as you've got the stock ports, main cat, air pump and acv, passing shouldnt be a problem

 

Not sure since I don't worry about emissions, and wackaloo doesn't say where he's from. But isn't there a visual inspection in some states? And since making that kind of HP would require mods like IC, intake etc., it could be a little tougher.
