Hey guys...
OK...that website address is
www.exhaustproslinc.com That's where you can get the Magnaflow from.
Bizest...the Magnaflow part # I got for the muffler was off of Husker's website. Upon further review, I see that they have a drop-down menu to select inlet/outlet size. Therefore...you are probably right, as you need a 2.25" inlet/outlet size. My mistake as I put the wrong one up

...I was just going off of Husker's site! My apologies!
Eric...$70 sounds pretty high...you might check around. Just tell them that it's a 20 minute job tops...think they might be trying to give you the shaft...
