Since I have a header and an axleback, that bigest gain is found in the midpipe.

FWIW, I ran 106whp/107wtq with intake, 2.25" crush bent resonator-axle section and a Megan axleback .....no header

Dyno's vary and can really only be relied on comparisons to personal runs....or if a stock yaris runs on the same day. That said, 100whp with the wimpy stock 1.75" midpipe makes sense...
