Primarily the difference is going to be that JBA is going to spend the $3-5k to get them CARB approved and probably sell more of them because of it. The SLR design is along the same lines and are ceramic coated as well and don't mess with the cats either. Hence the fact that their price is so competitive.

The problem for me is "grass is greener syndrome." I have seen the promised land but I know I may never step foot on it. To manufacturer the 1st set of headers , equal length, ceramic coated and welded by a master, it would probably cost $2,000k for the first one and it would never be legal. But they are oh so beautifull.

Hemi version:

how 'bout an update on the header situation? Did u fix the link??

... who?... what link?

aren't the factory oem headers on the VQ40 arlready tubular steel? there might be what...3 hp gain by doing the bends a little nicer.

I would never break the original seal and untorque the studs and retorque them which might stretch them out and cause an easier loss of seal and a leak later on for minimal gains.

now a replacement for the crack-o-matic 3.3l's might be a nice thing to have.

Eh? SLRs headers displace the primary cats completely, no way they could ever be smog legal.

Very true. I'm currently installing a set on my truck. The cats will have to be removed. The second set of cats remain, but they are practically useless. I'm considering replacing the second set w/ the first set, just to still have a functional system. Either that, or I'll put in a set of high-flow aftermarket cats. I'm not a greenie, but if I don't have to blow smoke, I'd rather not...

The second set didn't even exist before 2001 on the non-California-emissions models. They're all "California" as of 2001.
