Nissan 370Z Forum - View Single Post - Considering replacing H pipe on NISMO exhaust

Hello everyone. I have had my NISMO Z for about a year and I think it is about time for some HFC's. While considering replacing the entire exhaust system I have decided on keeping the stock NISMO system and possibly replacing the H pipe section. If I am correct, the H pipe section is only around 2.25 inches in diameter with the remainder of the system around 2.5 inches. I am replacing the cats with Berks. I think it would be weird going from 2.5 cats back to a 2.25 H pipe. I am thinking of adding a custom 2.5 inch H or X pipe to keep the diameter consistent from the cats all the way back.

Does anyone have any experience with this idea? Are there any aftermarket X pipes out there? Any info would be appreciated.
