Does the Headman Ypipe come with the 02 bung already installed??? Or do you have to weld one in??? Also, what kind of fitment quality issues have you encountered with the Hedman headers(longtube and shorty)???? I had NO problems with my tubular Hedman dual cat headers(68491), but am about to install some single cat with the Ypipe and was curious about what problems I might run into. Also, how hard will it be to make a dual cat catback mate up with the single cat Ypipe????????????

 

Mine had the o2 sensor fitting already welded in. The only problem I ran in to I needed to make a shorty sparkplug socket to get to the two last plugs on the passenger side. The way the pipe is bent, you can get a normal plug socket and wrench on but you can't back it out.

 

Mine didnt have a O2 bung welded in. Only problem i had with them was mentioned above, the spark plug, but that was no biggie.
