New Header on the market

[EFSleeper]

yeh it was unheard of for me to lose power and not gain torque. I had an ebay header before that I lost 12  whp but gained 23 torque but with that I gain nothing  So I'm anti bisi now

They look good but I dont think you can run them if your running a/c

Cool header, bro.

Mikeyspec on honda tech just did a header compariso n on this header. I was kinda surprised that the Toda V1 made the most power. The SMSP b19 did not make the best power but beat the Bisi copy.

The powerband was very similar to the original with just a slight shift downwards (I believe 2hp). If you look at the curve, this is definitel y a drag header lol. No midrange when compared to the hytech replica.
