Hey guys, I'm new here and I was just looking for some advice as I am thinking of either getting a single flowmaster super 44, or a single flowmaster 40 series. I have a 2010 and my entire exhaust system is stock and I was just looking to get a new muffler. Despite this, would there still be a significant sound increase in either of the flowmasters? Also, which do you guys prefer? Thanks a lot!
