Everyone knows, I think, that J's header gives the best up top gains.
But what about this Megan header for only $350 shipped? I really want it but I am unsure of the gains, and no one has dynoed.

Primaries

J's 50mm
Megan ~52mm

Secondaries

J's 55mm
Megan ~60mm

Collector

J's 65mm
Megan 63.5mm

This really looks good. Makes me believe it would gain decent #'s





These also look really good. No unwanted/needed bends. All piping is same length.



Here is a dyno the company did. Stock ap2. While I usually don't go by company #'s, these look feasible.

I am really thinking about biting the bullet because I really want a header before I tune my VAFC. Anyone in here knowledgeable in these parts? From all my readings, from a header, you want same length piping, minimal bends, and the piping sizes look good. Help me choose!

 

You want it get it. The HP gains are resonable. The stock header is good but if you realize 5 hp and you like it it is still worth it.

Go for it!


MODS, MODS, MODS!!!

 

on the bigger thread, alot of techs said all they did was copy the j's header, since thats all megan racing does anyway.

 

Ooooh, that's preeeetty.... where do you get it?

 

Check out the group buy forum.

 

Imitation is the highest form of flattery and cheeper too
Go megan racing 4-2-1 Is the best for N/A 4 into 1 best for FI

 

To add to that... equal-length runners are better for top-end power, staggered length are better for low-end torque.
