The TPR race header and midpipe are planned to be sold as a package, since the header is too long for the stock midpipe. It's definitely possible to get the stock midpipe shortened to fit the race header, but the 2.25" stock piping would result in restriction and power loss.
A midpipe to fit stock style headers (Trial, TRD, DC) may also be released, so even if you don't have the TPR race header, you can still gain the power of a 2.5" midpipe. Adding the TPR midpipe to any aftermarket exhaust would also be the equivalent of having a header-back exhaust, but would be much quieter.
