How was low end grunt compared to the 2 into 2? Thats actually quite impressive that it was only 4hp and 300 revs down on peak.
The pipe that was tested flollowed the 2-2 set up with in 2hp, + at times and - in places. The test wasn't done very well to be honest. It was just bolted on with out any fueling or ignition changes and run.

The pipe in the pic is a different design and designed in the sim differently than the pipe tested. IMO the other pipe was designed with an unrealistic wall temp. Time will tell lol.
