Your new pipe is going to have more low end power than the FMF, you just won't be able to tell because there's such a massive increase in power in mid-high end. It'll feel like there's less power there but that's only because you'll be spoiled to that extra power up top. It's not a scientific measurenent, but I was able to tow a dead blaster through the dunes in 3rd without getting on the pipe. The FMF was only able to tow it in 2nd ON the pipe.
