just went to auto zone cause cel came back on and it said bank one ctalytic converter. so im assuming that the first catalytic converter is messed up and causing my cel. where is the first catalytic converter located?

 

Exhaust manifold..

 

the 1st catty if your lancer is stock is the exhaust maniford or aka "stock header"

 

oh heyy i see you are in the 305!... get that lancer lookin and performing nice!!

 

yupp. so i guess got to make an upgrade to some performance headers. wut brand carries headers besides rrm?

 

KamiKaze makes a header and downpipe combo. I've had mine for a year now and like it for the most part.

 

basicly... when you mod... think about the future.. if you plan to turbo your car, then buy the rrm header. I have the rrm header and i luuuuuv it... JEeeYuh

if you want to stay N/A the kamikazie is just fine.. and RPW makes a damm good header too

 

rpw imho has teh best header. ive seen the difference in power between any shorty header and the rpw one.

the kamikaze ive never heard of.

 

yea im gonna look around for some headers this weekend but prbably end up wit the rrm or rpw ones. does anyone knw if the obx one is good found some on ebay?

 

has a factory recall on that cat. You can get it replaced for free...

Why not do that instead of drop money on something you don't need?

 

i just called tha dealership and they told me there was no recall on the warm-up cat.

 

i wouldn't go with ebay. RPW or RRM all the way. i really like my RRM headers.

if you need a stock manifold with a working cat i've got that if you're interested.

 

That's pretty interesting... looking at the TSBs, I guess that's true. For 2003, I see the cooling fan controller replacement, the PCM update and the O2 sensor problems.

Sorry for the bad info! Go buy a header!

 

the same question came up at school today....

i heard that we had 2 cats, so i looked under the car, saw 1 cat and 1 resonator

figured that if we really did have 2, the first one must have come off when i got my header installed

+1 for south florida lancer owners

 

I have same problem with the CEL and i had it Checked, same thing lol... Im just not doing anything about it.
