The car  was originally a 140 so does not have the cutout for the exhaust 
tip. I would  use a stock muffler but do not want to cut the body. Anyone 
have experience  with Magnaflow?Thanks,Jim Cuneo65 Corsa with turbo 140Sonoma

Jim - I have twin Magnaflows on my C6 Corvette. The sound is fine, but  
those sounds pass through a Cat Converter first, so this application may be  
deceiving. One of the problems you will find is that most smaller aftermarket  
mufflers are designed for replacement when increased noise is not a problem 
 (Performance is taking the lead). If you take the car to a good 
Performance  Exhaust Muffler shop, I'll bet they can find the equivalent of the  
original Turbo muffler - in noise and allowable back-pressure - in a  slightly 
shorter package. That would allow you room for a turn down.
