Brian,
i dyno'd the car for the first time yesterday and was very happy with the results. I have your header and midpipe and still use the stock muffler. air filter is also stock lay in. Got 155 HP and 141 tq. very nice gains imho. also, temp was hovering in the low 40's, garage door was open.
i highly recommend the GWR header/midpipe.

2010 Competition Yellow MX-5.
Re: great header/midpipe dyno, Thanks Brian!
Since he notes dyno was the first time, sounds like he didn't have opportunity to do before and after with similar results after the full exhaust. But many prior customers have done before and after and posted results. Some of those are in the dyno thread here....

not sure type of dyno, unfortunately, no base run. looking at a couple of muffler options, then i'll re do it at the same place.
