Anyone buy an aftermarket downpipe with an extra o2 bung WITHOUT a bung plug? If so, what are you guys using to plug it up? Would a simple bolt work, or is that just going to end up coming loose under heat????

I made plans to get this installed at my cousins, I'm bummed out right now

 

You have a pm.

 

bung plug.. that just don't sound right.

 

A Bung plug would work but, make sure not to get to big. You don't want to be stretching it out. I am surprised it didn't come with one. Also you can move the o2 sensor there if you want to.
