What is the first and best option for the money to get 15-20 more horsepower. I have 08 miata, automatic, thanks!

Behold the factory header, a product of sad cost savings, note the pinch point circled in red, tough to make power as the RPMS climb when everything has to squeeze through that point where the tubes are pinched almost in half:


So, the bad news is that the factory header is junk....and the good news is that it is easily improved upon with something like


RoadsterSport Max Power Header.



And you need the muffler at the end to keep the flow all the way out, we suggest our RoadsterSport Q with either choice.

I was hoping you'd mention what was up with these new titanium ceramic coated headers, since they seem to have hit the site in the last day or so...
