Only shorties are legal in Cali.

Long Tubes are just that......full length headers that are one piece almost all the way to the cat. Shorties have a seperate downpipe. It is widely acknowledged that LT's give the best return for your mod $$$, although some will argue.

I'll be following this thread, a local Corvette shop told me that Borla headers are certified but I haven't done enough research on it yet. My muffler guy said he had an issue with Borla shorties and they wouldn't return them, we're kind of limited with mods in Cali.

To have any major work done, I have some buds that go to Race Street Rally in San Jose.

I picked up my exhaust from the Corvette Clinic in San Jose on W. San Carlos.

There is supposedly a really good shop in Vacaville, Corvette Heavan or Corvette Express, they were originally out of Campbell Ca., but moved over to Vacaville.

The only place I could vouch for would be the two shops in San Jose, I trust my friend because he takes his ride there and so does his dad and they've always done right by them. The guy at Corvette Clinic has been there since '78 and is a nice chap and knows his stuff pretty well.

Depends on the car and which header.

Rule of thumb is usually 10-15 rwhp for shorties, 15-30 rwhp for LT's.

thanks for the info...the only place i know of is this place in Roseville. I think they are a supporting vendor of this forum, but i've never used them:

Be very careful the semi-annual smog test is not the only way the state busts non compliance. Street racing, random check points are only a couple of ways of getting into trouble. Fines are heavy and jail time is possible. The rice racers are favorite targets but anyone is fair game. I have been through this-NO FUN. By the way shorty headers aren't much better than stock exhaust especially Z06 manifolds. Some people have actually reported a power loss. -Bob

Where????

Never in my 17+ years in SoCal have I came across nor heard of an inspection checkpoint......

DUI checkpoints, etc, where they take a look at your license, etc.....but never where someone is gonna look at your car. Maybe it's an issue for the younger guys who frequent the midnight illegal drags.....but that ain't me.

I just finished an SB100 registration of my Cobra replica. Part of that process involves a BAR inspection and a one time only smog test(SB100 registration is forever after smog exempt). I had a very interesting conversation with the BAR district supervisor who administered my test. Yes, midnight street racers are a frequent target of sting operations but beyond that they have portable sniffers that they can set up roadside. Whether or not they will be able to detect a clean running late model Vette is debatable but take it from someone who has had a run-in with the BAR- it's expensive and nerve racking and when you spit out the other end you will be a believer. -Bob

LT's themselves don't increase emissions. Mine, as do many, have all the smog hookups and I run cats. The ONLY reason they're not legal is because they don't have a CARB number, and the ONLY reason for that is the manufacturers don't want to pay for or play the idiocy of the CARB game. They have NO EFFECT on emissions. Heck, there are MANY people passing smog tests with them ....they'll definitely pass a sniffer test and there's a lot of smog techs who either aren't sharp enough to know the difference or just don't care.

I don't know where you are or what your experiences are...but neither I nor anyone I know share your concerns.

This explains the difference between long tubes and shorties:
http://www.ls1tech.com/forums/showthread.php?t=139142

As for long tubes...I'll have a 4-way with Penelope Cruz, Jennifer Lopez and Salma Hayek before C5 long tubes are legal in California. So far the chance of that 4-way isn't looking good.

The B&B shorty headers have a CARB number and so are 100% legal in California. I just installed a pair last weekend...very nice headers! However, if you can't find a used pair (like I did) I don't feel the cost (about $1000) justifies the performance gain.

<I don't know where you are or what your experiences are...but neither I nor anyone I know share your concerns.>

Life is one long risk/reward balance. You will, indeed, probably never have a problem. I just want others here to be aware that modifications that make California certified cars non-compliant are discovered at times and dealt with rather strictly. If you get caught "I'm sorry" will not make it go away. It will be expensive. -Bob

FYI, I have a set of B&B shorties for sale. Excellent condition, 8K miles.
Made 12HP/ 14T on the dyno. $425.00 shipped UPS to CA. I went with long tubes and no cats. No way that will fly in CA, huh!
