These pipes replace the restrictive secondary catalytic converters with high-flow cats, allowing the 2.5T engine to breathe easier. While not offering major performance gains, the exhaust note will be drastically improved.
From stock exhaust system repairs to polished stainless steel performance exhaust, we have exhaust pipes, mufflers, resonators, and catalytic converters from the most respected suppliers in the business. Go loud, stay soft, look good with exhaust parts and systems from ECS Tuning.
