Hey Twag,
He's a long answer to a short question
When we started Ace we wanted to build a header that made 86 owners happy. We wanted people to love the sound, power, torque and have that awesome "whoo-hoo" feeling when you change gears.
Problem was, it was taking too long to deliver the Type A and people weren't getting that feeling...so we went back to the drawing board.
Thanks to awesome "beta testers" -you know who you are

, the Type B is almost identical in performance to the Type A.
CSG played a big role for this to happen, so we promised them we would build 20 final Type A's over the course of 2016 to fulfill their commitments with their customers.
We're confident that when people get their Type B's, that ear to ear grin and "whoo-hoo" feeling will come with it.
Thanks to everyone for the understanding and feedback.
happy driving
Team ACE
PS- rumor has it CSG is in development of a low-db, high-power muffler....just a rumor though...
