Finally after a lot of research, fitting, dynos, and correcting design issues I can offer this to the Mazda 2 community.

I have been authorized to sell these headers made by a pretty decent company called Speedlab. I had mine for more than a month, and besides the Check engine light issue (already figured out) it has been a blast.

A gain of 11- 12 HP and 11-12 Lbs. of torque when used with a full exhaust and no tuning.

The Kit comes with gaskets, bolts, O2 sensor extensions, and extra bungs in case of O2 sensor relocation needed.

Welding.









I have also developed a write up with pictures and instructions of the installation.

Cost varies depending on shipping: $ 330 + $ 90 for regular shipping (4 weeks)

$ 330 + $ 160 expedited shipping (2 weeks)

A GB is an option but minimum of ten units is necessary : $ 300 + $ 90 regular shipping

Thanks for looking

how do you get rid of the cel or check engine light cause im very intrested
Two ways as far as I know:

1- Custom tuning
2- Moving the second O2sensor to the back of the second cat on the exhaust, the kit will include a n O2 sensor bung, is like $20 to do the hole and welding. You will need to make a 4 wires 2' extension.

The header really works with a full custom exhaust with 2" and 1/4 diameter all the way to the muffler.
