Not to sure on the sound difference, they are loud because of my setup. ( kooks shorty headers, mrt Off road h-pipe and borla over axle). It really boils down to personal preference.

I have some new corsa sport mufflers I put on my non catted boss for about 20 miles but didn't like the sound if your interested. i'm going to sell them soon.
These have been on my car for 3 years all in great condition. I never installed cover from airraid for water getting onto air filter.
