Any Suggestions?

So I just put on my Mac Long tubes w/ the H-pipe and high flow cats. But, Mac performance said that it still will not pass smog? Will i just have to put my stock stuff on every couple years to pass it?

Anyone running long tubes, what have you done?

Unfortunately, unless you get a guy that doesn't check your car thoroughly.. you'll fail visual

Personally, I'd say find some friends locally, and find a guy who will overlook the visual part as long as you pass the sniffer

Thats the gay part about CA - My regal passed BETTER than average in every category, but would have failed for visual on about 10 visual mods

I ended up getting a stang just so I could get all carb legal parts and not worry about it anymore

Your best bets =
Going back to stock every 2 years
or
finding someone who will help you out..

Good luck in either case headers are a PITA on 99-04 cars!
