I installed my Helix FMIC and Stett Charge pipe this weekend and I was wondering why no other company has come out with an aftermarket up pipe? Have these companies seen no improvements in making an aftermarket up pipe? There are some dents on the stock pipe that could be taken out with an aftermarket pipe to make for a free flow design. I was just pondering why these companies haven't introduced something like this? It is really easily to remove if you're already swapping the FMIC.
