CNT res TP's broken!

fuct · 03-24-2012, 10:01 AM

I didnt say much about the slightly warped flange on the brand new CNT resonated test pipes i bought last year, or the fact that i bought CNT's SES engine fix O2 sensor extenders to fight the SES light that NEVER went away. but i will b!tch now since last night when i pulled outa my work parking lot i hear a wierd exhaust gas noise then pop! followed by me dragging my O2 sensor down the street.

i guess you get what you paid for......

What does this have to do with anything in TX? As long as there's no cel, you will pass with a straight pipe from the exhaust port on the head to the tailpipe. If you're really concerned, I'll send you to the place I went with my STI. They just don't care.

i always had a check engine light. even with the O2 extender and steel wool jammed in the hole. i figured i wouldnt pass with the light on. plus i dont have any tuning software to shut that off.

it worked out though. i went back to the factory cats and they are still in there. if i do anything it will be some FI or GTM high flow cats. also with out a tune the low end felt weak just running the RTP's.

Well? Sounds like a perfectly good excuse to go get a tune.

it looks like the extended bungs are probably causing too much stress on there. my CNT HFC's dont have this extended bung. the O2 sensor bung is probably 1-2inches long. stuffing steel wool did the trick for me. literally rolling a tightly wound ball and shoving it into the bung, then pushing the O2 sensor in.

im at 30k miles now with these on and so far so good. not trying to defend CNT/ERZ, but then again im in california, no salt or anything to worry about

i tried the same thing with out the extenders. i still had a check engine light. i then bought their over priced extenders and STILL got a CEL!!!

if anyone needs a large package of steel wool let me know! haha
