Hey guys, I haven't been on the forums in a while( for those of you who might remember me!

) but I had a quick technical question for you exhaust gurus.
What's the widest muffler you can fit where the stock resonator rests in the middle of the car?
The reason being my glasspack I installed 3 years ago has gone and rusted through on me. I picked up a nice looking offset magnaflow muffler on sale today, and the length looks about right, but I'm not sure about the width. Can anyone help me out? Oh, for reference, the muffler is 9" wide.
