if i get the dc jdm header will i have a problem using my stock cat?

 

yes kind sir you will have a problem

 

the cat would be too long i believe and you would need to modify it

plus the stock cat has a 2 1/4" inlet and the header will have a 2 1/5" collector, plus I believe the bolt holes on the flange wont line up properly, it's wider on the JDM header

 

the only thing you can use stock would be the stock cat back, the closest you can do right now is getting a new cat and have the jdm header, cat and you still can retain the stock exhaust but you NEED a new cat

 

jdm header is 2 1/2" in case that was a typo

 

good catch. hahah i didn't even notice that. i just read it 2 1/2 in my head.

 

do a search, there are 589769048576904857698576 topics archived about this

 

where's a good place to order a cat from

 

search function is your friend

anyway, mike@ips, dave@smsp, Leo@jdmsecperf?, RandD?

 

Actually, you can use the stock cat. You just need to weld a 2.5" flange on it and you may need to shorten your B-pipe.

Now whether you'd want to go to all that trouble and still have a somewhat more restrictive converter is for you to decide, but I had to point out that it <U>can</U> be done.

 

thanks for the welding info but wanna keep my stock cat intact.

 

does anyone make a JDM aftermarket cat in the US?

 

You will need a cat, you can go with a Carsound, or other types of Cats. Many people have Carsounds, but they seem to fail on most people, mine still hasnt. Or you if you want you can just use a test pipe.

If you want to pay a ridiculous prices on the carsound cats you can contact those people mentioned above, (which i did and regret).

Or you can go to a muffler shop and they can get one for you for a fraction of the cost.

 

anyone on the net sell a 2.5" test pipe w/ o2 sensor threads

 

go to a muffler shop get it made, specific to your car, again it will cost you a fraction of the cost.

 

will they be able to make it so there is no CEL?

 

CEL no CEL that is the question?
