I am thinking about an exhaust for my truck ('99 sierra 2500). Will one 3" muffler and one 3" pipe coming out in front of the passenger side rear wheel be enough flow, or do I need two mufflers and two pipes. In addition, if I exit my pipes in front of my rear wheel, how much more polishing am I going to have to do to my Alcoas.

 

im a big fan of just one 3 inch out the rear like stock that is what i ordered a long time ago like two weeks but havent got it yet will try to send you a pic when i do

 

That is what I like also. I think that I am going to try outletting the pipe in front of the rear tire this time though.
