Message Z1 downpipes and testpipes are unique and made only for Z1 to our specifications. They are not the sets found on e-bay and the like. The "E-bay / Megan" downpipes and test pipes ALL use piping that is 60mm OD. We use full 2.5" OD piping which is the standard for true 2.5" exhaust components.
The separated turbine outlet pipe on our downpipes is larger diameter pipe than any others we've seen. Our 4 bolt DPs are specifically made to accommodate a larger turbine wheel such as a sport 500, GT525, etc upgrade. We now include custom multilayer steel gaskets that we have produced to go with our 4 bolt downpipes. These gaskets in combination with our 4 bolt downpipes reduce the restriction resulting from using the stock turbine housing/downpipe gasket with an upgraded turbo (where the turbine housing has been machined out for a larger wheel). Unlike E-bay/Megan our products are QC checked and spot checked for fitment. Our DPs and TPs will actually fit without stressing other exhaust components. The picture you point out from our product listing was of an early prototype from years ago (noted by the sharpie marking on the flange). I'm now putting in a request to our parts department to change that picture to an image of product from current stock.
