Just so we're all aware, sound is the main thing you gain with a cone filter. HP gains are negligible at best.
I actually think it’s quite slanderous and unfair to accuse manufacturers of lying about their results without offering any counter proof of your own. Manufacturers spend a lot of money on these aftermarket parts in the R&D department and if you don’t agree with their results you should offer your own results. It’s not fair and I think the manufactures could find that is libelous.He is not wrong, I been following Mishimoto’s R&D very closely(who are very transparent with their progress) and they also stated that HP gains are minimal with dyno charts to back it up.
Again, why the condescending tone?
