WNLancer if you want to run a cat I suggest either get the HKS or Fujitsubo Downpipe because they both fit the 2005's with no problem. If you want to run catless like myself, and just put the stocker on when emissions comes up, I would either get the DC Sports or RSR. I would lean towards the DC Sports, because I have it myself and love it. It fit well with my Blitz Nur spec cat back.

 

i have the taper on my exhaust,will that fit with the DC downpipe?you said it comes with a CEL fix might go that route but,still open to other options,i want have JDM parts as possible.

 

just make sure it's a 3" dp. The RSR is a downpipe/cat delete pipe. it's ceramic coated too for better heat retention and less heat radiation to the oil pan. just use the spark plug antifouler fix for the o2 sensor. If i had the money when i was upgrading i would've gotten RSR or buschur stuff.

 

Where could i get the anti-fouler?does it involve splicing the O2 Sensor?

 

no splicing! check it out. Very easy fix for highflow cat or delete. I think it'll cost you less than 5 bucks. I've had it on for 3 months with no cel's.
