Description

The Cobalt Stainless Steel Muffler is engineered to enhance the driving experience of your Mazda MX-5 Miata. The construction includes 1.2mm thick 201 stainless steel for the muffler shell, tips, and piping, complemented by a 409 stainless steel inner core and perforated tubing. Muffler packing combines stainless steel wool and fiberglass to produce a sporty yet unobtrusive exhaust note, ideal for a sports car. The unit features CNC-cut stainless steel flanges, a beautifully shaped oval muffler, and a sporty 4" polished tip. All welds on the muffler are ground smooth and polished to maintain the mirror shine. A gasket is included for installation. This muffler is specifically designed for the 1999-2005 Mazda MX-5 Miata models with manual transmissions. It comes with a 5-year warranty against defects in materials and workmanship, covering the original purchaser and vehicle, provided there has been no physical impact. Moss Motors also provides a general 12-month warranty on all products sold.
