In case anyone hadn't seen this:


Test & Tune: 2005 Mazda RX-8


I had to manually step through pages 1/2/3 in the url. But they showed gains that are higher than what people typically claim from RX8s. I'm always hearing "the RX8 doesn't gain much from X/Y/Z modification", but this shows very solid gains.


BASELINE 180.8
TEST 1 Race Muffler 183.0
TEST 2 REVi Intake System 190.0
TEST 3 Test Pipe 196.5

Perhaps the ECU was still learning the catback exhaust? Or perhaps it's some other artifact of their test procedures?

 

With those parts I can believe it in a perfect world scenario on a dynojet assuming they did not screw with the dyno between runs.

 

It's possible another Matt did, but yes I did email you.
