Watson's had all the smog stuff but are NLA.

Call Stainless Works see if they can make a set with the AIR tubes.

Other choice would be cut off stock AIR tubes and have them welded on headers.

Well these had all the smog stuff, but it was all welded shut and ground off then they were ceramic coated. I love these things, and no lt-5 should be without headers.
Before I put these on and the fidanza, the lt5 was kind of boring after having the lt1 and lt4. the 2 mods completely transformed this car. This is a very powerful engine.

Yes...Yes they are. Your next forray should be to P&P the top end.



(I damn near swallowed my teeth, first time I whacked the throttle last spring! I have to feather the throttle in first, and it squirms like a snake in second now!)

Gawd, I love these engines! Soooo MUCH return for relatively simple DIY mods!

There are NO long tube headers made for any smog compliant vehicle that are legal in California. The only way around it is to stuff the LT-5 into a 1972 or earlier car...... At least for the moment. Who knows what those bastards in Sacramento will try next. damn SOB's!

Doesn't matter if they have all the fittings. They do not have a CARB approved number on them.

How does CA or other states account for the need to replace Cats? No replacements, so there has to be a rule or way to address this. Is there not an exemption..all else fails get a damn PO Box in IA, SD or some place.

I figure if it passes emissions then your good to go.
A visual is a whole other story.

In IL if it passed there was no visual.
I thought the same for CA.

In IL they did away with OBD I emissions
When IL had emmisions for OBD I there were ways around it like show car, basicly insure it as a show car limited miles (3K year)
