I know that this has been asked many times, but things change over the years, what is the best muffler for a supercharged cobalt. I want a deeper sound. Right now I have a mandrel bent exhaust with stock downpipe and resonator with no muffler

 

I know you said muffler but id do a full exhast. its hard to find a good sounding exhaust for the SC's. if i were you id try and find a GMPP exhuast. to me one of the best sounding exhausts for the SC or the Corsa. pricey but great sound

 

I know this 1! Just got done swapping exhaust over and over. The zzp 3 chambered muffler. It's expensive but great. I love it
