I was curious to know what fix G owners have done when replacing their cats with free flows or test pipes. I am specifically talking about 04 models and up, as they seem to have these issues with the CEL. I just ordered my Crawfords and I have a 04.5 GCoupe and I know I'll throw a CEL. Will a Technosquare ECU tune take care of this? if not, what are my options besides 02 Simulators, which look to be my resolution. Thanks!!!

You have to bore out the set that the O2 sensors plug into to a diameter of 1/2" so that they will fit inside.

Worked for me, but I'm not giving any guarantees!

 

Seriously, what is up with these posts you are making?!

 

FYI guys. My post above was to a person who has probably had his message deleted by now. He was spamming us.

Thank you, drive through.......

 

Hmm, I have Crawfords (and other stuff, read my sig) and have not thrown a CEL. About the only thing I did do was when I had the front passenger seat out to put some dynamat on, I connected the battery to check the stereo wiring, and my airbag light came on. Easy fix, and nothing to do with the cats or the CEL...

Maybe you'll get lucky and not throw a CEL

Hey Eldy, thanks man..that looks good!!! i should have them this coming up week and I'll give it a shot...thanks for those pics...ill keep everyone posted..

 

I have the Crawfords, absolutly no CEL issues. Great fit, just make sure they're installed properly, keep the MAF sensor clean

 

i have not had a CEL with either my old Kinetix high flows or my newer Crawfords... you should only get a CEL with test pipes

 

the cheapest and easiest way to fix the cel light....help method.

I have these and they work. I even them installed them and I don't know chit about cars.

 

Getting the cats tomorrow..but I had a quick question...if you drill out the inner part, how will the o2 sensor screw in?? the thing will be bald from drilling, right? Or, are you just drilling with 1/2" bit to make it a straight through design and the thread will still be on the o2 plug..

 

Don't know how to explain cause I am not mechanically inclined, but if I figurged out so can you. If you use the 1/2 inch drill bit it will not mess with the threads. There is something that looks like a washer in the middle. You need to drill that out. If you have a vice it will make life a whole easier.

 

The "wall" (1/4" hole) that you drill through is only roughly 1/8" thick. Once you get the parts you'll see that you're not touching the inner threads.

 

nice...you're right, i got the parts and it makes sense..i feel like a jack@ss for even asking..anyways, My fujitsubo Legalis R FINALLY shipped and I should have it by Wednesday...ill get both the cats and exhaust installed together and I'll definitely post pics and vids..thanks guys!!

 

installed test pipes and the fix and NO CEL so far..over 150miles...looking good...and OMG, the sound is ridiculous!! very loud and raspy from 2.5thru4.5 rpms....but definitely feel the car pull harder!!!

 

So wat did you end up doing finally? You used that anti spark plug fuller?
