dyno graphs stock exhaust and full exhaust

[ukraine]

Hello Everyone.
Today we did some dyno runs here in Ukraine. we used dyno dynamics 4wd dyno (2000hp win based) to dyno the car. remember it is all FLYWHEEL HP. now wheel. the wheel HP we got is 430whp. All runs on same fuel. Exhaust is Magnaflow. downpipes JMB. Also can has KN intake.

Here is the pic of the car:

here is the base run with stock exhaust

here is the run with exhaust

here is compare graph.

as you can see the gain is 43 hp.
Can anyone comment those numbers? Are they correct?
and also what amaises me, on the AFR graph you can see that car runs soooo rich. 10.3 to 10.6 AFR! Which amaizes me. Shouldnt it be 12.5-12.8 ? Anyone can assume what kind of power can we get on 12.8 AFR?

I thought you got flywheel HP off the back of the motor on a motor dyno and when you had your vehicle on a chasis dyno that was wheel HP? But 43HP for changing you exhaust is an excellent gain!

all the dynos have a correction to calculate the flywheel HP. The RWHP with no exhaust was 400 and with exhaust it jumped up to 432
