High flow midpipe kit for your 2022+ Subaru WRX. Available in three versions:

• RO-CPVB-N: 3" center section without Resonator. Splits to dual 2.5" at the rear.
• RO-CPVB-C: 3" center section with Resonator, 400mm x 120mm (15.7" x 4.7") straight through high flow resonator which aids in sound suppression. Splits to dual 2.5" at the rear.
  
• RO-CPVB-CS2: 2.5" center section with Resonator, 400mm x 120mm (15.7" x 4.7") straight through resonator plus internal sleeve for additional sound suppression. Splits to dual 2.5" at the rear.

All versions bolt directly to OE downpipe/ J-pipe.

• RO-CPVB-N and RO-CPVB-C have full 3" center section and do not have a reducer to bolt to the OEM J-pipe. The OEM donut gasket must be removed and replaced with provided flat style gasket. This configuration will also likely fit aftermarket 3" J-pipes.
• RO-CPVB-CS2 with the 2.5" center section bolts to the OEM donut style gasket.
