H-Pipe questions
 

When I installed my off road H pipe I reinstalled the stock O2's but I heard theres a kit to bypass those but is it worth it. Also I wanna plug the outlet hose that goes to the smog pump although I still have my smog pump installed I hears you just stick a bolt in and silicone it up.

You cant remove the O2 sensors and you would not wnat to. They are what the ecm uses to monitor air/fuel adjustments at all times except cold start and wide open throttle.

Put a spark plug and a clamp in the rubber hose coming off the air inlet tube on the h-pipe. Stuff it in there, it wont leak and nobody will see it.
