running a 63mm berk test pipe and it comes with o2 fix for a while without a cel. size depends on the exhaust you run

 

this is far from the truth. a lot of the cheaper ebay test pipes do not fit properly and will throw a CEL. i had a berk test pipe on my 03 and never had a CEL. quality and fitment was top notch

 

I never had any problems with my berk 63mm. Now that I have a r1000 I am just using spark plug defoulers and have had no issue with them.

 

sarcasm, my friend.

I mean adding the defouler to the non-CEL fixed TPs. I dont have experience with the CEL-fix included TPs so cant tell you how that works...

 

I added two defoulers onto my megan test pipe and have never thrown a code. Ever. Took very little time to make.

 

I am supercharged and running fairly rich, I had to add an extender to the Berk test pipe w/ built in fix so I don't throw a code. So I essentially have two extenders.

 

if you have an 06+ and you have hondata i think you can disable the secondary o2 sensor so you wont get a CEL. but dont quote me on this.

 

does smog check pass with a tp..?

 

If you live in CA, it will absolutely fail. You would need to swap the OEM cat back in before the smog test

I have an '08 with a T1R resonated test pipe (63 mm) that has the O2 fix built in. I've driven hundreds of miles without a CEL. I believe the resonator actually helps the mechanical fix do it's "thing".

I also have a FlashPro that does have an option to desable the secondary O2, but I haven't tried disabling it yet.

 

As some members have mentioned before, the T1R is a great test pipe. T1R offers both 63S resonated and 70R nonresonated, both with defoulers and 02 bungs to fix the CEL problems.

If you need any pricing, feel free to PM me or give me a call at 604.279.0329! Cheers.
