I dyno'd my Stage II in November and added APR downpipes over the holidays. Over the weekend I went back to the dyno to see the difference. As you can see the DP's added ~11HP to the wheels, but close to 50 ft-lbs of torque. For those on the edge about downpipes, I highly recommend them. The car is definitely quicker, with faster spool-up. Next stop... stage 3!

This was on APR 93 octane by the way. 93 octane fuel too.

Sorry it's kinda hard to read, didn't realize the Picture Poster would resize it.

Not another person trying to get Stage III in the area. You guys are forcing me in a corner here.

Wow look at the torque jump up.

if only APR had updated software for the other boxes besides the M box...

Your base runs are taken to a higher rpm than the DP runs. Any reason why?

They can't use the optical or inductive pick ups to determine the redline so they have to calibrate it of the rollers.. ALl it means is the lines to go to redline but the numbers are still accurate

Just the way he set up the dyno that day... shut it down a bit sooner this time.
