We have finally had a before and after dyno.
Before anyone screams false, I'm posting the actual company doing the dyno in the actual graph.
The only issue with the dyno run is that the run before the exhaust was put on was done from 4K RPM up, while the post Exhaust install was done from 3K RPM and up.
I had DSR point out the differences on the graph from the start points so you can see the max differences in value.
Other than that, the dyno was run within 1 hour of the first dyno. So the conditions were almost identical.
As you can see, our exhaust DID make HP gains. Peak gains of 10 Torque and peak 7HP.

We just received more exhausts, they are waiting for clearance through customs.
They have the same beautiful rolled edges that the current batch has. If anyone wants more photos, let us know
