Anyone using this test pipe and it's claim of not triggering the cel light?

 

i use it, works great, no check engine light in the last 15K miles.

 

yes it really works. I love my UR test pipe. no cel in 4 years.

 

buddy of mine has it, works perfect

 

yup, 2+ years. no CEL

 

thanks for the comments gonna purchase it after the positive responses

 

another person with no cel. Had it on my 8 and now the 9 not one cel

 

yes its an excellent product. awesome power, fitment and no CEL

 

can anyone explain how this pipe does not cause a CEl to be thrown. Is there an 02 bung on piipe that is welded so it causes o2 sensor not to stick so far in causing no CEl to be thrown. Is there even a spot for the 02 sensor on a test pipe. Very curious

 

manufacturers secret. don't ask. don't tell. Just buy it.

How much is this product? I gave basically $50 for my ebay test pipe, used a $4.50 de-fouler from autozone, havent had a problem.

Put it on 50 miles later CEL, put on 2 defoulers in addition to the already welded spacer got a CEL. I must have something wrong.

 

Been using it for a year no problems. Really nice piece.

 

2 years....works
