another one, i want one with the bungs or w.e with no extra cost because if you add up all the little options that test pipe charges then its like getting an AP test pipe.

What's so unique about the Ultimate Racing Test Pipe that is doesn't get a CEL? Does it include a Spark Plug Anti-Fouler or is it something with the design of the test pipe?

ours is 249$ shipped but IMO its well worth it. Its a straight piece of pipe instead of curved, it does NOT throw a CEL, It has an extra bung for a wideband, Its 100% SS. Comes with hardware and gaskets.

CEL= Check engine light. These test pipes won't throw a CEL caused by catalyst deficiency. Meaning these test pipes are able to trick the ECU into thinking it still has the Cat on the car. The way they work is they only allow the o2 sensor after the cat to see limited exhaust flow.
The way the Ultimate Racing test pipe works is it puts the o2 sensor in at an angle instead of strait in therefore it essentially cuts about 50% of the exhaust flow from its view.
