Just get a custom cat back at a muffler shop it will be cheaper...just get a universal exhaust and get it done at a shop. It will perform the same as a Cat-back system..

You would probably have to order the EX cat back since the DX is different.. Remember you are going with an Ex setting and not a DX setting

 

Ok thanks a bunch man...I now understand!! lol

 

i did that on my 02. you need an ex header, ex downpipe/ cat, and an ex catback, unless going custom.im running cat-less on mine cuz we dont have emissions testing here, but you will need the extension wires for your 2nd o2 sensor
