Hi,

My '99 WS-6 has some pretty good mods now - 224/230 cam that I'm told should just squeak by smog, LS6 intake and AFR 205 heads. Now I want to do something about my constipation, since I still have the stock exhaust. Since I'm in CA, I'll have to pass visual smog inspection, and I figure I'm limited to shorty headers. What else can I do? I'm thinking about some hi-flo cats and maybe a better Y-pipe. A cat-back system would also be nice, but I don't want to go too loud, since my wife drives the car sometimes and my neighbors like quiet.

Anyhow, I would welcome some suggestions from other CA members based on their experience.

i am pretty sure they are illegal because they move the cats. But does anyone know people who get away with using them as long as they have cats and all the air ang egr?

Didn't that dude with the black firebird just put them on and say they were legal?

Oh well. Then the OP will have one of two options:

Edelbrock (or co. of choice), SLP 2.5 Y-pipe, and high flow cats.

or

Go old school find a (look the other way guy) and go full on LT's, ORY, (maybe gutted or HF cats to ward off nosey officers)

You are correct, mids are illegal still, just as much as long tubes. There are shops out there that will pass you with mids/LT's as long as you have in-tact cats and the rest of the emmissions equipment, so I've heard.

Your best bet is (I guess) going to be shortys to a 2.5" y-pipe. Bullet muffler after the merge then maybe a couple more before it exits the rear of the car. That should keep u legal and quiet while giving u some more breathing room. Don't expect the kind of power the guys with bigger headers are getting. I'm thinkin u should've went with a cam that was designed for stock manifolds/shorties.

I also have some shorties off a 2000 that I am looking to get rid of, but if he wants to pass the underhood visual inspection they will not work on his '99. Ask me how I know lol

Thanks for the suggestions. I would like to buy shortys from someone, but it looks like the 2 sets offered were for a 2000. My '99 needs different AIR/EGR flanges.

Shorties are a waste of time, money and resources, Mids are still considered illegal so I would just jump to full blown LT's and a catted or ORY...

Call a few shops make a few friends and smog will no longer be an issue...

With a catted Y pipe the car would still pass smog just look for a lazy smog operator who just throws it on the dyno and runs it...

Pacesetter has a set of "mids" that are legal. I quote mids b/c that's what they call them, not sure if they're comparable to what other manufacturers call "mids".
