Headers for 2003 Tundra

I've been searching the aftermarket vendors for a nice set of headers for my



4x4.

So far, TRD has nothing for this application. (I understand that the 2002s won't fit.) They're ridiculously overpriced anyway - especially for non-equal length primaries.



SS Autochrome has a set available in stainless steel, but they haven't responded to my query re smog legal for CA. Also, not equal length.



Downey has a nice looking set, but they aren't stainless. They appear to be equal length, or close to it, which is a big plus. They _say_ they're 50 States smog legal. They offer a ceramic coating for some extra $$.



So far, Downey sounds like the best overall - but I sure wish they were stainless. What say you all? Have I missed something? TIA.

which ever you go for, make sure they have a CARB number. lots of smog shops have to be *shown* that the parts are legal.

I believe that JBA, Downey, and TRD are the only CARB certified headers for the 4.7.

S&S Headers will soon have long-tube headers available for the Tundra, but I don't know if the 2003 will fit. These will not be CARB certified due to the high cost of certification testing. They will be 35-1/2" long primary tubes, new high-flow cats, and replace everything from the heads to the circular joint in front of the muffler.

photo is a pre-production prototype set of headers. S&S Headers is norelation to SSAutochrome.http://www.ssheaders.com/ Ceramic coated headers will keep heat out of the engine compartment and keep heat in the exhaust for better performance. I'd rather have well-coated carbon steel headers than non-coated stainless steel headers, and forget header wrap...it'll allow the metal to overheat and fail.

Thanks for the good info, Ken. Unfortunately, that first link requires your password and user ID to access on a secure server. :^(

Also, the link on the ssheaders home page for their online catalog is dead.

I may decide to go for the Downey ceramic coated headers. They require some welding to install. Do you know a good local shop (Glendale-Burbank area)? TIA.

Thanks for the tip, Mike. It's been a long time since my hot rod days, and back then the only CARB to worry about sat on top of the ENGINE! :^/

Ceramic coating is definitely the way to go. Preferable from a reputable company like Jet Hot. The only thing that concerns me is the "welding required". That seam is going to be ceramic-free and if it's not stainless then it will rust to high heaven. Stainless will still rust, just not as bad. Is this for some kind of cross-over pipe? If so, what exactly is the purpose of this pipe and what would be the problems with leaving it off?

S&S is not certified for CA, and due to the costs, will not be.
