Will short headers improve performance?
Hi all, I've got a C6 LS3 A6 base with a CAI and am wondering if adding Short Headers will improve performance/hp and are worth the cost? I live in CA so long tube headers are not an option. Thanks

Yeah Cali is checking for tunes now too. I agree with you space, i think c6z exhaust is OPs best bet if he wants to do anything.

The z06 manifolds many have said offer a gain, plus, as for Calif, may pass the visual portion of the smog test.
I believe Hooker brand exhausts makes a Calif legal shorty header.
As for gains from shorties, perhaps. There is certainly a weight loss and exhaust tone improvement.
Yet as noted, a "tune" will not pass Calid smog inspections.
As a next step, hi-flow cats that bolt right up to the chosen exhaust may also offer some gains.
Yet, I am unsure of smog legalities and inspection passing if installed.
Good luck with your decision.

Hence C.A.R.B legal shorter headers, but here is the rub, and with even shorter headers that scavenge better, unless you can tune to richen up the top end during WOT ( since the motor is going to lean out), then your not going to gain the full 10hp that you could with them.
So the CARB #D-115-20 only covers you on the headers themselves to be legal in CA on the car, but not to have the car after market tuned to take advanced of the headers isntead.
With the super charger kits, they are C.A.R.B legal, as well as the manufactors tune that comes with them as well.

My friend of almost 50 years, who lived in CA for 40 years, finally said screw it, and moved to AZ. Easier to do when you're retired, like he is. But it's one way around CARB. With all the problems in CA the last few years, you would think they'd have bigger fish to fry than checking if your tune has been altered, or not. If a car passes their sniffer test, wouldn't common (uncommon?) sense tell you it's sufficient, whether there's a 250hp V6 under the hood, or a 600hp V8, instead? If it's clean burning, its clean burning......EXCEPT in CA.......

I have the hooker shorties. Idk if they are worth the price honestly, I found mine used and I had to modify them to fit (so much for direct fit).
I can tell you that it’s a true 3” collector unlike my LS2 manifolds.

Hell, just a mater of time until Califorma air resource board starts going after electrical car parts and upgrades as well.
Hence they make a ton of money by the after market manufacturers having to get Carb numbers to be able to run the after market parts on the cars in CA, and can see them with pushing for all electric cars by 2035, will be going after them next to stay funded. Hence by then, people will be cracking the electric car os's, not only to free opt into manufacturer performed upgrades, but to better then a well.
Since this is going to cause the cars to have less mileage per charge, put more of a burden on the power grid with all the extra charges, will be a point that they will be checking the electric cars firmware versions to make sure they are stock, and maybe, even get to the point that they block even the Tesla's own pay for performance upgrade as well.

Why should the green weenies get a free pass on road constrction, maintenance, etc.? They already get a tax break when they buy their cars.
But, it wouldn't be a fair tax, it would probably apply to everyone and be an additional tax.
And according to newscumb, we're not technically broke. We can just borrow more $$ and let our kids bail us out.
