Racing Beat Y-Pipe for all 1986-92 RX-7 Applications This Y-pipe is a perfect replacement for a failing stock component. The Racing Beat Y-pipe is slightly larger in diameter than the stock non-turbo Y-pipe, and matches the diameter (2.5” O.D.) of the stock TURBO II Y-pipe. Therefore, if you are replacing the silencer(s) on a TURBO II application, and unless the original stock Y-pipe is failing, there is no performance benefit to be gained from the addition of this Y-pipe.
This Y-pipe includes the Cat-to-Y-pipe gasket. Manufactured from heavy-walled steel tubing and chrome plated for excellent durability.
