I'm rather new to tuning, excuse my ignorance. Cats taste like shit, even with teriyaki. I work at a Ford dealer and found some core return Cats that are bad. I was going to go cheap on performance gains, not going to happen. I am presently speaking with a company in California to develop a turbo back exhaust system to replace poor quality factory parts and hopefully gain more powers
Anyone else in California interested? I know, **** California.
