04 EM2, second o2 sensor?
 

Hey, i'm thinking about getting this
Headers then a cat/resonator straight pipe

i am only expecting minor performance gains, but my question is, since this removes the CAT (not an issue here, no emmissions control where i am), anyways, my question is, am i going to have my engine light come on because of this? i know in my other car (GM) i needed an o2 simulator when i removed the cat because of the second o2 sensor, which is after the cat and is only to notify you that the cat is not functioning properly.

please dont buy those. please.

Why not?... if there's a legit reason i'll listen, but just saying "don't buy them" really doesn't convince me of much.

because there sh!t ebay brand man. i have megan racing header, with a downpipe and catback exhaust. and yes if you get rid of the cat and the 2nd o2 sensor, you will pull a CEL. mines been on for 4 months now. i would just convert your exhaust to EX and get a good brand header like DC or megan. (i have an 02 EM2)

What's it take to convert it? just a header and downpipe?

it is correct, those parts are absolute pewp.

Care to elaborate? i just do not udnerstand how you can screw up soemthing that just allows gasses to flow through it... do you ahve any personal experience to back these comments up with?

RE: 04 EM2, second o2 sensor?
 

first off, watch your mouth.


and yes, ive been here for quite some time. if you were to research just a little bit you will find people who have had experience with parts that were equally as crappy as these. welds break, things dont fit etc.... you get what you pay for so go ahead, be a cheap tight ass and buy these. but if you want quality, save up. megan header is $125.

RE: 04 EM2, second o2 sensor?
 

what do you mean by that? i never said anything mean or offensive, i would just like more than "dont buy those", like i said, if there's a legit reason, like you just provided, i'll listen and take it into consideration, but "dont buy this" isn't very informative or convincing.

if you wanna powertrip and ban be for expecting a decent answer than feel free, it's not like this is the only forum around.

all im saying is if you post a link to something you want, dont expect opinions. noone is power tripping.
