Kenny might have some. I know he was trying to sell his exhaust so I dont know if he had some pics of them taken.

Nice numbers Eloy.

If I read the second chart correctly, it shows that horsepower-wise, the RPI and Supersprint setups are relatively similar but one system dips a bit after 7260rpm (I can't tell which one as the colors are so similar).

Also, seems like the RPI setup has a significant increase in torque from 3000rpm to 6000rpm (approximations).

Correct?

You probably know this Josh and just messin with Kenny but they're using a Dyno Dynamics which shows very conservative numbers.
