A bad muffler leads to heavy noise on the road, and the inevitable drop in performance means weak idling and much less power for your daily jobs. A Nissan D21 performance muffler from AutoZone eliminates rust and minimizes the sound of combustion. Deterioration also creates holes in your system, but a performance exhaust muffler for Nissan D21 actually keeps toxic gases out of your breathable cabin air.
