Need help with High-Flow Cat

Hi.  I'm new to the forum but I've had my Civic for a couple of years now and I'm hoping to get a little help...  I've tried using the search option to do some research, but for some reason it's not working right now.

I bought a Magnaflow 94036 H/F cat for my '96 Civic Ex Coupe since I was replacing the whole cat-back.  It's a 16", 2.5" in/out, oval body cat with the O2 sensor located at the rear on the driver's side. The dimension were exactly what I needed but unfortunately there was a little snag.

The stock cat has the O2 sensor located in the rear of the cat as well, but it's on the passenger's side.  The wire for the O2 sensor wouldn't reach the connector, and the floor plug wouldn't reach either.  On top of that, the angle that the sensor hole is on makes it hit the shield and it won't let you flip the cat either.  The direct fit Magnaflow cat would be great, but it's only 2" in in/out diameter.

I know that there are a LOT of people who have installed h/f cats on their cars so I'm hoping that someone can suggest one that I can use.  It's needs to be 16-16.25" in total body length, with 2.5" (or even 2.25") in/out, and an O2 sensor in the rear on the passenger's side.

Thanks  

*** the sensor bro.....lol, seriously just zip tie it out of the way so it doesnt melt with the heat of the header
