I just installed a MBRP pro series cat-back dual exhaust system on my 2010 Silverado. To be honest, I'm a little disappointed in the loudness and sound of it. I was hoping for more. I wanted an exhaust that was really loud, with a nice, deep tone. This one just doesn't do it for me. Is there anything I can do to make my truck louder? And, I have heard differ opinions on this, but do larger or smaller diameter exhaust pipes make the system louder? I have heard people say each way makes it louder, which is it?! The exhaust system I have uses a 3 inch pipe from the cat to the muffler, then after the muffler splits into dual 2 1/2 inch pipes out the rear of the truck to the tips. Any help or suggestions would be awesome!!
