LG Super Pro headers without cat question

I have an 02 Z06 with a Magnuson supercharger. Has anyone in California ever gotten pulled over with long tube headers without cats? Is this a fix it ticket or not a big deal? Can they make you remove the headers? My car is not due for a smog check until after I leave California.

I am moving to Hawaii in June and taking the car. I want to install these headers before I go. No emissions in Hawaii!

Thanks,

Andrew

Yes, I have been caught and was sent to Smog Referee station and had take my long tubes off and put on Shorties with an CARB EO #. It really depends on who pulls you over and if the cop is a dick or not. But officially long tubes are illegal.

If your exhaust isn't loud, chances are you won't get pulled over......unless you're doing something really stupid in the car.

I say go for it.

It's only an issue if they check for them. Most do not, but some may. Just keeping you in the know.

I have LG PROs w/no cats now H/C/I and stock TIs and it's still pretty damn loud. My friend has catted Dynatechs (same as Design as LGs) with same size cam and a supercharger on his Z06 and it doesn't seem quite as rowdy even though he's got Borla stingers. Cats make a big difference during normal driving even with long tubes, less at WOT but if you get pulled over going wide open it wouldn't really matter much.

I am actually upgrading my LG (catted) Streets to the LG Super Pro's (no cats) with my H/C/I and Corsa Indy's... I am guessing mine will be pretty loud..

Are you getting it re-tuned after the swap? I'd love to see the dyno comparison, and I'm sure I'm not alone.
