So i am looking at purchasing a test pipe. does the ultimate racing test pipe come with a bung welded in?
this one here

or do i have to get that seprate. and will this bolt right up if i have a megan downpipe and a jaspeler catback (or something like that i dont know the name exactly)?

 

Doesn't look like it does...most will say in the description if they have a bung welded into it or not. It should bolt right up if you get the pipe the same diameter as the rest of your exhaust....just make sure you get the gaskets for it as well.

That was in the description so i figured maybe it has a spot you can put it in or something? anyone know any good cheap test pipes with bungs
