I have an 01 2500HD that I am looking to put dual exhaust and new tires on. First the exhaust. What would be better for tubing size? I want a deep, mellow tone and not a high pitched, popping sound. The next thing is I don't know weather to do straight out the back, or out the sides at 45 degree angles. What size of tips do you think would look best? Next, tires. I was looking for an aggressive tire that will wear well. I drive a lot of old back roads, and a lot of snow and mud and ice.

Thanks for all the help, this is a great forum!
