Re: precats/smog
I ran 'piggies' for a year (but didn't go through driveclean.
With that being said, here's the deal
precats control only cold start emissions. Therefore if you get your car nice and warm (15minute+ drive) and take it to the emissions test, it will pass no problem.
I'd book an appointment, then sit there and wait. That way they'll get on it right away. If you leave it there all day, it may be a problem.
Piggies pass emissions in California...the toughest emissions standards on earth. Just make sure you go in warm.
p.s. if you need a set of already 'piggied' MT6 downpipes, I have a set of JHM piggies for sale for $250. You can just trade me your stockers + cash for the JHM ones.
