Ultimate Racing Testpipe
i have one nothing special ur better of gettin a o2 sim cleaner install cause with the UR test pipe u have to extend the o2 wires. You will be better off getting and normal test pipe and using and 02 sim. trust me it will end up working better and with less of a headache.

An o2 sim is a box that has resistors in it that gives the ecu a signal that the o2 is working so u never have a check engine light. With this u can remove the o2
the UR test pipe has a little passage for the o2 so that the o2 never reads the dirty air and signals a check engine light.
if you ask me the o2 sim fixes the problem at the core and the UR test pipe just covers it
once again you will be spending more money for something that u don't need too
