What would restrict me to shorties, and what is the advantage of LT's?I think you may have to stick with jba shorties and put high flow cats behind them. Long tubes are the way to go if you can get away with it.
Your stock exhaust manifolds have catalytic converters welded to them where the manifolds meet up to the b-pipes. If i have understood the California laws right, you cannot change the catalytic converter location from stock which is why you need the JBA shorties and hi flow cats. You have resonators in the b-pipes and they are unnecessary.What would restrict me to shorties, and what is the advantage of LT's?
From what I gathered in the "exhaust sticky", it seemed that my model/year doesnt have cats up near the manifolds...did I get that wrong?
I'm sure there are people on here that have gone through the trial/error and could spare me the headache of doing the same.......pleeeeease?
Pretty pretty please??

I will Qship
my setup is nismo longtubes, into 2.5" b-pipes to a single 3" y-pipe then my turbo maybe a foot or two after thatI agree... If your running the Vortech than you might want to go with 2.5". The collectors on most of the headers is 2.25", so you could step it up to 2.5" in the B-Pipes. I don't think there's been enough testing done on the Vortech SC's to really be able to say what the best setup would be.![]()
If I was you... This is how I would do the set up from the JBA headers (CARB legal and comes with sticker).Thanks to all that posted. I really appreciate the advice.
So, JBA shorties, h/f cats and 2.5".
Has anyone tried this with forced induction and not had issues with burning up the cats? I have been reading that this a problem even normally aspirated. Really concerned about damaging the engine.
Also, those cats that were suggested are 49 state- anyone know if I will get by the sniffer in Calif?
One last question please. Where is the best deal$ on this?

Yes Michael, your pestering did the trick![]()
