The aFe Takeda 2-1/2in 304 stainless steel cat-back exhaust with polished tips (MPN 49-37015-P) replaces the factory system from the catalytic converter back to the rear of the vehicle. It is listed for the 2014-2018 Mazda 3 with the 2.0L and 2.5L four-cylinder engines. Its 2-1/2 inch piping and 304 stainless construction are the main reasons to choose it over a stock or mild-steel aftermarket system. Stainless steel resists corrosion better than coated steel, which matters for owners in road-salt regions, and the polished tips give the rear of the car a finished look.
Searches for a 2014-2018 Mazda 3 2.0L or 2.5L cat-back exhaust, 304 stainless Takeda cat-back, or 2-1/2 inch Mazda 3 exhaust with polished tips point to this part. Confirm fitment against the manufacturer's application list for your exact model year and engine before ordering. Because a cat-back replaces only the components after the catalytic converter, the factory header and converter stay in place. Check the manufacturer's install instructions for the required hangers, clamps, and any hardware, and confirm the included parts before starting work.
