The shorties do help with sound quality and noise, not sure on power though. Everyone seems to think they know what shorties do, but no one has brought a back to back test to really show the difference.
I would love to have LT's.

Why are you asking if they will do a visual check for the long tubes?
I have NEVER heard of the headers themselves being illegal.
Get long tubes and keep your cats. Everything will be fine.
I believe you need an updated tune also to turn the rear 02 sensors off with long tubes
or you will get a couple of CEL codes for cat efficiency

My JBA shorties is one of my favorite mods. Sure they don't increase horsepower like long tubes, but my butt dyno felt a low-end torque improvement (mine is a daily driver). The exhaust sound is deeper and smoother with them also.
IMO most of the LT gains come from the O/R mid pipe or HF cats that most people put on when they install long tubes. You could install shorties and leave your factory catted H-Pipe on for inspections and then easily switch out your mide pipe to an O/R H-Pipe for the rest of the year.

Most of the aftermarket cats that are anything but OEM are crap and will not pass in california.

BTW you don't need to get LT's coated if you get a real set of headers like American Racing. Buying that cheap Chinese JUNK you may want to consider it.

i was just searching on a couple forums and i came across people talking about their longtubes and not passing a visual...one guy said as long as u pass the sniffer test than your fine, but if u fail the sniffer then they will fail u on the visual also. I was kinda just trying to verify if anyone else has heard of this. I have never done full exhaust before and just wanna make it legal without any worries....so if i get the longtubes and a high flow catted h pipe with a tune so i dont throw a CEL than i should be legal correct????

Visual?? Please if you find somebody THAT strict that wont pass the LT's they wont pass shorties either as they are not OEM. Find another inspection station.

If you have anything on your car that is aftermarket in regards to the intake or exhaust, it will not pass smog (visual). This is unless the person behind the machine knows how to open his pocket and look over some things.
If you have ever had ceramic coated and regular, you would know why ceramic are better.
