Sounds good.
I have the Librands exhaust but also the manifold. The manifold made a big difference in flexible torque across the range but especially at road leaglish speeds in 3rd. I drive it now often for the sound & sacrifice MPG for enjoyment.
Oldbill also a TM regular found the same effect.
I also have a K&N but in the original housing.
Mine is a T16.
I am sure a better ECU would help
