Anyone using this exhaust combination? I know the WORKS 76mm downpipe comes with an o2 adapter for the stock o2 housing, the outlet on the oem o2 is 2.25 inches, the eBay o2 housing is 2.50 inches.

 

I just put one on my buddies car this weekend. It does work. It was hard to get the adaptor on the o2 housing, but we finally pounded it on with a mallet. I wouldn't say that the ebay o2 was .25" bigger than the stocker though.

 

Bump to see if anyone else has any more info on this setup. Any issues on installation?
