Thank you all for the information. With the information I was able to ascertain that the exhaust is stock and not TORS. I have contacted David Platt and will "fix" the cat issue for good. Custom Silencers with Performance Pipe. I will then do a re-tune. Any suggestions on the tune I should go with for this setup?
