Yes all 4 pipes were tested on 2 quads.
Other threads will be posted with those dyno graphs with the HPR-19 and the DCS, They will be posted as there own Dyno runs, we did not want to just post graphs and start the Dyno Pipe War again, As for myself the testing was just for research, cant fix what I dont know is broken that's what the testing was all for, I am still on the razors edge on making anymore pipes, the only reason for making the DCS pipes were for members that just cant afford $800 to $1000 pipe.
As for Dale, he will explain his reasons.
