Show original supplier description
The DC Sports Universal Oval Muffler (DCMU-300-ST) is engineered for custom exhaust applications, offering a versatile solution for enthusiasts looking to modify their vehicle's sound and performance. Constructed from durable 304 stainless steel, this muffler boasts a 3-inch inlet and a 3-inch outlet, making it suitable for a wide range of exhaust system configurations. Its oval design and straight-through core aim to increase exhaust flow, potentially leading to improved performance and a more aggressive exhaust note compared to stock mufflers. The sound level is described as moderate. Adaptation to a particular car will likely involve custom fabrication and installation. The manufacturer advises that if you are unsure about fitment for your specific application, it is best to contact them for guidance.
