all the dyno results had similar results and very consistant. All dyno pulls are always measured from 4th gear, hence the higher rpms.
Just to be clear... the dyno sheet shows that the RPi exhaust makes nice power over the stock exhaust throughout the powerband, but actually makes less power after 6,200 or so RPMs (and power falls off quickly after that as compared to stock). That seems odd, but may be explained if timing is being pulled due to heat soak...

The exhaust sounds pretty sick. Way better than all the other fart cans I've heard.

Congrats guys...looks and sounds very nice. Great job! Not sure if this was mentioned somewhere in the thread but how does this exhaust atttach to the outlet of the downpipe? I haven't really looked under there but I'm assuming there is a fitting/joint that allows this to bolt on/off?
