tsudo exhaust

Hey guys I had a quick question. I was looking to buy a Tsudo catback exhaust system for my 2009 cobalt. After looking on different sites for the best price I found one for $280 and one for $250. I will include the link to the two but I'm just curious as to what the sound difference will be...

Ok, I looked around and could not find an answer. Is the tsudo exhaust long enough to fit on a sedan or do I have to get it altered. I know about it hanging too close to the bumper i'm talking about length.
