The Series II modular architecture lets you mix and match mid and rear sections, so an owner who started with a Series II EP Dual rear can swap to this MBSE rear section for a more refined dual tip configuration without buying a whole new exhaust system.\u003c\/p\u003e\n\n\u003ch3\u003eCritical Compatibility\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eONLY works with ISR Series II exhaust systems.\u003c\/strong\u003e This section will NOT bolt up to the factory OEM E46 exhaust or to the original (pre-Series II) ISR exhausts.
