Sorry for the slow reply. I installed JBA Speed Shop headers. They are sold nation wide and his shop is in San Diego. Yes, a true 70 foot pounds of torque! I also had Ed Hanson Muffler shop replace the exhaust cat back to illiminate the choke point where both two and a half inch pipes went into a two and a half inch pipe and instead has a "Y" connector to a 3" pipe. Then larger muffler. Go to my photo album to see pics.
