anyone using them or heard anything good about them? do they really work opening the ports or is it just bs? cause i'm lookin to get them! also i've noticed that when my ports are wired i have to start my car with my foot on the pedal a little and without them wired turns on fine. this happen to anyone else?

 

I have the header sitting right here. I won't have it on for awhile, have to figure out whats wrong with my car first. I do believe they work, Mazdatrix has never been known to "BS" anyone. There are some other people with them, mazdaspeed7 does I believe.
