It's also corroborated by our discussion (mine and longboarder's) of Malek@MRF's car which is putting down slightly higher than 400 HP to the wheels, using nothing other than the MRF (full) exhaust) and a tune. No intake, no pulleys, nothing else.
But, if you're talking about N/A gains over AKRA, then that's another story. I'm not aware of any dyno's of the MRF Midpipe compared to an AKRA midpipe on an N/A car. I'm assuming this is the situation //M3THOD was referring to when he said doubtful. While i wouldn't go so far as to say doubtful, I would reserve judgment for a proper dyno on an N/A car.
I meant over an akra. I already have test pipes on my car, but if this were to give 16hp/16torque MORE, then that would be exciting! But sounds like this will only benefit SC cars
