The sport and the street x pipes are VERY similar in volume. The main difference between the two is the placement of the cats, the street leave the primaries in, where the sport has HFC closer to the X pipe. But, in the e9x M3, that doesn't make a huge difference in volume.

It will be a pretty good approximation.
