I use to have 60mm testpipe with no CELFIX, I fixed the issue by putting a spacer to the O2 sensor (non-fouler). Now I got the 70mm and I bought it with CELFIX, it turned out that the fix is embedded ?!? Isn't this restrict airflow? I mean the whole idea of the Invidia N1 exhaust is that it has less weight and minor curves for minimum air restriction?!?! Then why did they do a testpipe with CELFIX from inside?!?!?!

From the inside? Every test pipe Ive seen has the O2 bung sticking out from the test pipe sooo Im a wee bit confused on what you mean

What the hell, my 60mm Invidia test pipe I got a few months ago wasnt like that! Iv never seen one like that before.

thats the 70mm cel fix pictured above. mine has the tube inside the tube i guess to "shroud" the o2 sensor. however it doesnt work and you still need to do the non-fowler mod to get rid of the cel. ive been thinking about this too recently and thought about taking it out of there somehow

Is it possible to take it off ?!

Ive definitely never seen a test pipe done that way before. Here are pics of my berk test pipe. Most others Ive seen are setup this way too





As far as removing it I don't really know if you can. If you remove that shroud on the inside it'll definitely throw a code. Then again as stated above someone had an issue with it throwing a code anyway. I would definitely look into getting a berk. Ive had mine on for a few months now and have never gotten a single CEL from it

That is extremely odd, I have never seen that. I had a 70mm Invidia TP with the CEL fix and it was not like yours, it was like the others pictured here. I do not like that new design.
