So you are left with a heavier unit that does not perform as well as it should. The there is all the added heat the extra piping adds.
I would bet that a properly modified stock Y-pipe would easily outperform this "equal" length unit and it definitely would do it with a lot less heat transferred to the oil pan, engine bay, p/s lines, and underbody.
They claim a modest power gain over the stock Y-pipe. Well I should hope so. Even a flawed design such as this should be better than poorly crushing two 2" pipes together into one 2" flange. Thus effectively making each pipe under 1"!!!
Your best option for a Y-pipe is modifying the stock unit. Followed by a SHO/BAT unit with a chip or MSDS unit.
The gains that performance fords are claiming is with an aftermarker ypipe on.
