Show original supplier description
The Techtonics Tuning 253-465AH is a 3-inch aluminized cat-back exhaust system engineered for a range of Volkswagen Mk4 models. This cat-back exhaust system fits all Mk4 1.8T, TDI, and VR6 engines. It is not recommended for the N/A 2.0L 8v engine. Buyers can choose from various options for the connection to the cat/downpipe, including 3-inch, 2.5-inch, or the standard 55mm size. Additionally, tailpipe options include hidden, visible without a cutout, or visible with a cutout. It's important to note that the visible tailpipe with a cutout may not fit all rear valances, and custom fitment could be required in some instances.
