Contrary to what manufacturers claim about stock exhausts, our testing revealed that upgrading the exhaust on a 2012 Scion tC can bring serious gains. I’ve personally installed and driven with the DNA MOTORING CBE-MU-STC11 Stainless Steel Cat Back Exhaust, and the difference is instantly noticeable. It produces an aggressive, deep tone and boosts low-end torque by 15-25 horsepower—perfect for city cruising or carving mountain roads.
This system’s 2.5″ mandrel-bent pipes and durable TIG-welded construction mean it’s built to last and resist corrosion. Compared to the other options, it offers better flow and performance at a more affordable price. While Borla’s axle-back sounds premium, its over $600 price tag is hard to justify unless you want the absolute best sound quality. The Northeastern stainless steel muffler? Good budget choice, but it doesn’t deliver the same performance boost or durability as DNA’s system. I strongly recommend the DNA MOTORING for a perfect mix of quality, power increase, and value—tested and trusted by me.
