Why do you have that plug in the test pipe? If you move your o2 sensor to that bung it does not throw a code.

 

yeah right, that was the whole selling point on the UR test pipe, the mechanical fix is built in. you just have to make sure its facing the right way.

 

no the mechanical fix i made.. bout 10 dollars at autozone.. had to dremel the inside of the fouler for the o2 sensor to fit.. if you use without the extra piece, the o2 sensor is gunna pick up too much gas flow and therefore throw a code

 

That is incorrect.

UR did extensive testing and I know you only joined back in 05 but when they first started selling evo parts they were the company to be for that part. It does not throw a code. Other testpipes do and need that trick you mentioned but this does not. I've run that same test pipe in both my 03 and 05 evo's and with stock ecu and with the utec with no issues ever.

 

ultimate racing had a older version of this test pipe which had an arm for the o2 sensor for it to run leaner which is what you may be thinking of ..but either way, i never got a code so i guess i did something right
