Several people claim that the Megan Racing Header has realistic gains and is the most affordable header out there, but it stops at that. I can't find any proven dyno sheets to show me. So as it sits, all the testaments, all the claims are simply generalities. Can somebody resolve this question for me?

 

Wong section. But no. Its junk. Mugen/berk/idk because none add more then 5-10 whp anyways

 

Are you looking for gains when partnered with a supercharger? Hint: Please say yes....but even then, they will get you

 

Yes. My car is supercharged.

 

11 psi novi1000, aem, 1000cc injectors, and a 66mm test pipe

 

Usually when things are hard to find it's because they don't exist.

 

I can say i gained 15 whp with my authentic js header. Its the only header i know of that is widely known for increasing hp

 

I should note that was on a f20 aem ems n1220sl at 11psi

 

the berk has been proven on the dyno

 

I just went turbo so I have a thermal coated black BERK header if your interested pm me
