UR test pipe
yes! that's what keeps the CEL light from coming on. It works because the sensor screws into the end of the bung and with that elbow doesn't sense the extra air flow, it just tricks the sensor! I have the UR test pipe and I love it!
all you gotta do is extend o2 sensor wire,takes like 15 minutes then the UR test pipe is good to go ,i havnt got ses light and ive been running for probably like 2000 miles catless

About 1200 miles for me, and I didnt cut the wires to extend them, you can pull them out there is slack in the wires tucked in under there. I love the test pipe, IMO it made a noticeable difference and my exhaust sounds sweet now, definitely a lot deeper
