Autoexe 2.3 liter 4-2-1 header - Mazda 6 Forums : Mazda 6 / Mazda Atenza Forum

Was wondering why or maybe u have plans but why not make a more affordable version of the autoexe header you guys sell. like same design but extend it down with a flex pipe to matte up to the resonator. like f2's but a 4-2-1 design yet actually made for the 6 and not focus/3 adapt crap. just thought i would throw it out there since alot of us were dissapointed with f2's performance.

I think the only way to really validate the F2 header is with an intake manifold like the Cosworth one since it basically flattens the torque curve and pushes the horsepower further up. The F2 header has more top-end benefits but a good 4-2-1 header would still be a better option, I think.

We have had a few requests over the last year for a header for the Mazda 6. It has not been enough to go forward with building one though.

What if we did got enough interest going ? Cause i mean there needs to be a better header and i wish i would of new you guys wanted more interest or had even thought of making one with enough of it. Let us know im sure you would get alot of interest from here.

I'm interested in the 4-2-1 header with a downpipe though to remove the choke point.

Do you mean a header that would remove both catalysts?
