who runs no muffler? straight piped??

straight piped sounds a little loud right? or am i just paranoid .. i am thinking about putting a muffler on because it seems like its a little obvious without one.. is it just me?

I like mine much better with a muffler. Its not bad without unless you are pulling a load, I couldn't even roll my windows down while towing.

I didnt run one on my truck for a year and it finally got old. I put an aeroturbine on and it actually lowered my EGTs. Best muffler I ever used.

I've heard good things about the aeroturbine muffler, it gets rid of the hairdryer sound.
