Installing Momentum Headers

AlexRaymond19

Good to know! I have the extenders from z1 on my z1 tp's. But they are like 3 inches long i think, so maybe its different. The hole in the bottom of the extender is like BB sized, and with the amount of steel wool i packed in there i think its not getting enough flow, but i could be off base. the code description does say "under performing cat" which would lead me to believe that the sensor is reading too much flow. What size steel wool is best to use? I got some medium fine grade, wondering if i should get the ultra fine grade to blow flow better. Is there a point where it will throw a code if it is not getting enough flow? If not i will just block the hole completely with a solid washer like disk and then put the sensors on.

Side note, i got my wheels re-torqued today along with and alignment and now my tpms sensors are doing the minute long flashing thing and then staying on. It did not throw an error before this. Is there anyway they could have ****** my sensors up just by tightening my lugs?

TPMS is strictly tire pressure man. Check your tires and make sure they are above 30-32 PSI. I forgot when it signals the TPMS to turn on.

If its flashing at him, he's got a sensor malfunction. Alex, did you buy new TPMS for the new wheels or did you just transfer over your original sensors? Some Nissans will need to be relearned after switching sensors or even after some simple work like rotations and rebalances. Just depends on how long the wheels were off the car for. Sometimes a quick scan of the sensors with the scan tool while they are on the vehicle will reset the sensors too. Also, our sensors don't alert us until the PSI drops below 26.
