Will this fit my 2010 Nissan Sentra?

It fits select versions of the 2007-2012 Sentra, including Base, Custom and 2011-2012 Elite trims. Check your trim and engine against the Nissan part numbers 20100ET000 and 20100ZE90A before ordering.

Is this a direct bolt-on or does it need welding?

It is a direct-fit muffler assembly cross-referenced to the original Nissan part, so it is designed to install in the factory location. Universal mufflers need fabrication; this one does not.

Will it change how my Sentra sounds?

No. It is a stock-style muffler built to restore factory exhaust noise, not a performance muffler. Expect the original tone back, not a louder one.

The muffler assembly itself. Mounting hardware and gaskets are not listed, so plan to reuse or buy them separately.

How does it compare with a universal muffler?

It fits the factory pipe routing and hangers for the listed Sentras, while a universal muffler needs cutting, adapters or welding. The trade-off is that it only fits the applications listed.

Our take on the AP 7559 Exhaust Muffler Assembly

The AP Exhaust 7559 is a direct-fit replacement muffler for select 2007-2012 Nissan Sentra models, cross-referenced to Nissan part numbers 20100ET000 and 20100ZE90A. It is a stock-style muffler, so it is built to match the original fit and quiet the exhaust rather than change its tone. That makes it a sensible choice for a Sentra owner replacing a rusted or blown-out factory muffler who wants original-like sound and fit. Against generic universal mufflers, it saves fabrication and welding; against performance mufflers, it gives up any sound or flow gain.
