Thread: Speed Daddy Headers and Smog

from the factory it only came with one cat. then a resonator, then the mufflers.

ca is messed up with approved headers. you can still run a cat, and the egr vale can still be hooked up. so all the factory sensors are stil used.

no idea if you pass inspection.

the other way you can get close to headers and pass inspection is a front plog, and a 3 inch catted down pipe. not as good as headers, but better then stock.

headers come with a down pipe. some are sold with a cat, some are sold without one. aka off road pipe its called.

you can install a cat if the speed daddys headers dont come offered with one.

Well CA state inspection does allow high flow ones. I know magnaflows are 49 state legal. Lol the one state being CA but I think maybe flowmaster just changed theirs to 50
State legal

walker are stock replacements, pretty sure thats what ca wants to see, factory parts.

the only set of headers CA will let you ever have is from "The Other Guys" header and you have to tell them your from ca to get your EO sticker.

here is a link that will help you out a ton on the hole EO number. From what I looked up last year you couldnt run an IC it was Illegal, also too CA thinks they own your Cat as well you cant touch that if you want to drive on the roads out here.

had to edit this because i didnt have the right link

last year when i looked it up it said that the other guys header were ca approved but to shell out 899 for a set of headers is way way way to much

here found this on there for ya

Look up flowmasters cats I can't find the answer on my phone

from what i have heard the EO number is nothing more than a sitcker

Couldn't you get SLP headers that will pass CA specs? Since those could come factory on the car.

they want that little sticker with some numbers.
