Im new to the site and still havnt managed to figure out how I set a profile pic. Anyways, I am thinking about finishing my exhaust off. I have a Flowmaster muscle truck exhaust on my 2001 sbsc silverado. It has about 150,000 miles on it and the cats are starting to rattle. I also think its time to lose the stock manifolds and get a little better flow going. I have seen Dynatech header and ypipe combos with cats for about $1400. I dont want to spend that kind of money and get something thats not worth it. Anyone gone down the Dynatech road? Thanks
