CORSA's 21321 replaces this portion with a full \u003cstrong\u003e3.0-inch Double X-Pipe\u003c\/strong\u003e, providing a smoother, less restrictive exhaust path.\u003c\/p\u003e\n\u003cp\u003eThe upgrade isn't only about flow. The dual-crossover arrangement changes the way exhaust pulses from each bank interact, creating the enhanced scavenging effect CORSA specifically targeted during development.
