The "high flow cat" in that auction isn't even a real cat converter. It's just a resonator.

That means if you used it, you'd fail emissions inspection.

 

wellllllllllll.... i dont know why people try to get so high and mighty and nock ebay cheapies. i got that megan 4-2-1 header for like 50 bucks and i feel the same way about it as any other one. piping is piping to me.

as to the smog passing etc... i cant help ya... out of state car in cali = no smog check for me.

 

wait until you get pulled over and they send you in for inspecion and you get a fine for illegal smog mods,

 

get some holley airmass headers they are carb stamped right on the 2 runner i got mine on ebay for like 115 stainless steel look thats ceramic coated too they look nice and perform just like my old dc headers

 

but they cant because its an out of state car. i dont have to get smog checked. its the beauty of it.
