JM auto racing was very helpful with any questions I had about the exhaust and ordering. The price was great and I chose apexi being it seemed like a great fit with out a lot of adjustments. I had to wait a while being it was coming from Japan and it was on a container ship at the time. But JM kept me informed of the status of the shipping. Only complaint I had was with the shop I had install my exhaust as they missed one gasket that needed to be installed behind the cat a metal ring like gasket and trying to trace the problem on why it had a hiss. Once found everything performed great. I would order from JM auto racing again in no time at all.
