After many hours of research I chose the Corsa because it is supposed to be quiet and have no drone....Well...
OMG what a brain rattling, nausea producing drone noise from hell! Cruising under very light throttle and load it was quiet as a mouse. Put your foot in it a little and at some rpm's and load it sounded like someone mounted a 12" subwoofer under my truck and pumped 1000 watts to it buzzing the whole cabin. My theory is the muffler skin is weak and it vibrates like a speaker. You hit it with your hand and it sounds like a hollow bell. Piece of crap. Being that the thing wasn't cheap, needless to say I was very disappointed. Its on it way back to the vender now.
Another thing worth noting is I never really looked at the exhaust on my truck. It has a very nicely mandrel bent tubing that looks to be nearly 3". Looks like top notch quality. I'm pretty sure I will never touch the exhaust again. Already waisted $150 in shipping. I guess I got to learn the hard way. sheeeet!
