Ensure the exhaust is cold before removal, and support the rear section while the centre pipe is changed. Check clearances carefully, as a larger single pipe sits differently to the factory layout. Inspect for leaks and recheck clamps after the first drives.\u003c\/p\u003e\u003ch3\u003ePackage Contents\u003c\/h3\u003e\u003cp\u003eThe listing implies one single midpipe as pictured.

Midpipe changes can noticeably increase exhaust volume, and New Zealand vehicles must meet noise and WoF requirements. The owner is responsible for compliance.
