race pipes and test pipes not street legal?
I was just on a z site that said that the race pipes ar not street legal becasue the cats are deleted. I wasnt aware that they did that and was wondering if the test pipes are the same thing. I saw some clips of the test pipes and i think it sounds mean as hell with a cat back.

test pipes and race pipes are different words for the same thing. Basically a straight pipe instead of a cat. both illegal.
Actually high flow cats are not legal either... (not sure on the RTs though, but don't think so...)

Lots of misinformation is being spread regarding this. Here is part of the US Code regarding emissions:

Here are some key lines:
No action with respect to any element of design referred to in paragraph (3) (including any adjustment or alteration of such element) shall be treated as a prohibited act under such paragraph (3) if such action is in accordance with section 7549 of this title. Nothing in paragraph (3) shall be construed to require the use of manufacturer parts in maintaining or repairing any motor vehicle or motor vehicle engine. For the purposes of the preceding sentence, the term “manufacturer parts” means, with respect to a motor vehicle engine, parts produced or sold by the manufacturer of the motor vehicle or motor vehicle engine. No action with respect to any device or element of design referred to in paragraph (3) shall be treated as a prohibited act under that paragraph if
(i) the action is for the purpose of repair or replacement of the device or element, or is a necessary and temporary procedure to repair or replace any other item and the device or element is replaced upon completion of the procedure, and
(ii) such action thereafter results in the proper functioning of the device or element referred to in paragraph (3). No action with respect to any device or element of design referred to in paragraph (3) shall be treated as a prohibited act under that paragraph if the action is for the purpose of a conversion of a motor vehicle for use of a clean alternative fuel (as defined in this subchapter) and if such vehicle complies with the applicable standard under section 7521 of this title when operating on such fuel, and if in the case of a clean alternative fuel vehicle (as defined by rule by the Administrator), the device or element is replaced upon completion of the conversion procedure and such action results in proper functioning of the device or element when the motor vehicle operates on conventional fuel.
So you can most definitely replace your cats with high flow cats as long as they still perform the proper effect. You can state that the old ones weren't working well enough and so needed to be replaced. The installation of test pipes is illegal though as you are removing a cat and replacing it with something that does not perform the proper effect. That being said only the act of removing the cat and replacing it is illegal. Once it is on the car, if you don't have emissions testing, it is perfectly legal. They would have to prove you put it on there and knowingly removed the cats. Its a thin line between illegal and legal.
