does anybody know what brand there pro billet distributors are? there prices are half what msd is. if there rebranded pro comp junk there overpriced

The two Jegs Billet's I've had are made by FireCore. I have one one my 340, dad has one on his 440. No complaints, they work and are easily adjustable.
