You can have this muffler removed. It is unecessary. My brother had it 
removed from his '92 CorradoSLC, with no resultant problems. It has a 
nice sound, too. If you had your removed (thereby solving your knocking 
problem forever), I would suggest replacing your stock muffler at the 
same time. The reason I suggest this is due to the fact that while I'm 
sure that the stock muffler will handle the added pressure of having the 
intermediary muffler removed just fine this would be an ideal time for an 
exhaust upgrade. Get a Borla muffler, or something else that the other 
list members can suggest. Most aftermarket exhausts do not require an 
intermediary muffler, so you should be fine. Problem solved, and a nice, 
new muffler to boot. Just my two cents'.
