After my Gibson cat back rusted out I had my local shop do a custom system based on a stainless Borla single in/dual out. That was over 15 years ago and it's not only still intact but the best sounding system I ever heard on a Dakota. I still get compliments on it. As for headers, if you can't get long tubes it's kind of a moot point. Shorties don't do much. The "Y" pipe is the biggest killer, not sure anyone is making a performance version anymore. Might have to go custom, but it's gotta go.
