Thank you for having what I was looking for and at a excellent price. I'll definitely be buying more off your website sincerely, Darian McMillan...
Installed this on my 2012 MazdaSpeed 3. This unit looks really great out of the box. If done right the install will pay out in the end. Make sure you thread the 5 bolts up top evenly. Also take good care of the o2 sensors because they are very fragile and you dont want to get any codes when you first start her up. Stock unit was a pain in the ass but the catless went in with ease. Since there are no cats the temperature under the hood was greatly decreased. I did not log BATs but i knew i felt a huge difference in temperature. Now on to the power. Big gains with this unit and i have that subie rumble. NO CELs too. I love it.
Thank you CNT
Installed catless DP, and what a difference. Quality product at a great price.
