I did a search on this, but i didnt find what i needed to know. If i get this carsound cat, will it effect my emmissions?? Would i still pass emmission with it???

Also i heard many things about peoples warning lights or something coming on becuase of the cat, is this problem fixed now???

And, which model should i get for my 94 integra RS (non-vtec)??? I am getting dc sports headers, carsound cat, and apex-i n1 exhaust. Which model cat. should i get. I know that it is gonna be 2.5 inches, but i heard stuff about 2 different models for the 2.5 inch flanges??? I dont wanna have to do modification to the b-pipe, so which one will bolt right up with the headers and exhaust???

Also, would you guys reccomend dc headers??? Do you have any other favorites for headers???

I know someone with a RSR exhaust, Stock air intake, and JDM 4-1 headers(which are not smog legal) and he passed!

 

I believe you would still pass emissions with the cat, since the idea of a high-flow cat is to improve flow while still removing pollutants; otherwise everyone would just get a test pipe. I'm not 100% sure about this though..

 

Very very nice selection of pieces you are going to add, with the exception of the header. If I were you, I would go ahead and slurge on a JDM Header, or one with a 2.5" collector such as Hytech or SMP. I just finished the installation on mine and this thing is bad. Much more torque and after 5000 or so RPM it hauls *** so much more. Plus you'll only need one end of the cat modified, since both ends are already 2.5". BTW, almost everyone I've heard said that they passed with a header/car sound cat. I haven't had any check engine light thus far.
