This would have come in handy when i bought mine........well actually the money saved would have went towards Uprev to get my truck running right after header install.
After the tune it ran like a raped ape compared to before. I like my headers, however i would tell everyone up front they will be losing some low and mid range until getting tuned.how did it do after the UpRev was installed?
hopefully this new change will help those that do not already have our headers on their trucks....so far the response has been good

That one always gets a laugh out of someone!!!!!!! :rockonhahah NICE - you got all the sale guys laughing at that one
But if you submit the part to Sacramento to get it tested WITH the new cat (production version), they will just test it to make sure it doesn't put out any more emissions than the OEM, and thus grant you an exemption!I hear ya on the install issue with the factory cats - Toyota FJ, Tacoma and Tundra owners with the 4.0L application have the same issue :bangit:
Unfortunately if we do anything that includes an aftermarket cat we could possibly loose our CARB certification since the parts will no longer be "cat forward" - which federal law mandates you cannot change the location of the cats, or o2 sensors ....technically it wouldnt change the location but because it starts messing with that particular component it raises eyebrows of the people that regulate those components when you incluse a cat already welded up to the header
