    Fmf is still doing it

    The power core 4 was a secondary choice because I could not locate a factory anodized exhaust that I was really looking for. This being said, the power core 4 has really great build quality!! I installed it on a yz250f with a power bomb header and it sounds amazing! I was skeptical about any power increase but I have to say that there is definitely a mid-too end gain with the header. Go with the mega bomb if you’re looking for bottom end gains. Overall, very pleased with the fmf system, thank you to fmf for all the years of California made quality performance exhausts!!
