hey guys got a couple of ? for ya'll. One is it possible to run dual exausht(full or cat back) on a 2005 4wd expy? If so is it possible to turn out at 45deg. behind rear tires. And what is the best sounding all around exauhst for the money...The only reason i'm asking on the duals is on my 2000 expy they can't do it beacuse of the rear anti-locks....any info would be great thanks
