Re: '93 90S Cat breaking up

["Scott Sierakowski" <audi90quattro@hotmail.com>]

My cat was under warranty when it went @74K miles, 2K miles later (off 
warranty) the other side went.  I was told by the muffler place this "most 
likely" happened due to the different flow rates of the cats.  It made sence 
at the time.  At that time I replaced the stock ones for hi-flow cats for 
$300.  It made the car a little quicker and has not affected gas milage or 
anything.  Just my experience.
