I just had a quick question.. now that i have the exhaust pretty much hooked up with the exception of the muffler outlet pipe and tips i was curious.. my h-pipe has 2 holes.. 1 on each pipe.. now my guess is that they are there if you were going to use o2 sensors or whatever.. but being as the programmer shuts those off i no longer need sensors there.. if i remember correctly there was something i read about purchasing bolts that close up the hole.. just wondering where i would go to get these.. thanks

any 18x1.5 plug should work.

 

I would personally just put the O2 sensors in there, hooked them up and shut them off with a tuner. No need to buy some plugs if you still have the old O2 sensors, which are basically free plugs.

Its what I did with my O/R H pipe.

 

same, i turn the rear o2's off on my performance tunes and leave them in, odd thing is i get better fuel econ(on my economy tune) with the rear o2 on and no cats?!?!
