Show original supplier description
The Milltek SSXAU120 is a performance-oriented cat-back exhaust system engineered for the Audi S3 1.8T quattro 8L models from 1998 to 2003. Its construction utilizes aerospace-grade T304L stainless steel, ensuring exceptional durability and resistance to corrosion and discoloration, promising a virtually unlimited lifespan. The pipe diameter measures 69.85mm (2.75 inches), and it features twin 76.2mm special tips. Milltek Sport has a long-standing reputation, founded in England in 1983. Their exhaust systems are designed, developed, and hand-finished in the UK. The manufacturing process employs advanced equipment like CNC mandrel benders to ensure constant radius bends for optimized gas flow and enlarged bore diameters over stock for ultimate performance without sacrificing mid-range torque. The acoustic development process aims for a sporty and crisp tone, free from NVH, drone, or cabin resonance. It is important to verify fitment details with the manufacturer's website before ordering, as Milltek does not accept returns for incorrect orders. While this system is made in England and comes with a 2-year warranty, it is noted as 'Sin Aprobacion Europea CEE y Suiza (CH)', meaning it does not have European or Swiss approval and may not be road-legal in those regions.
