The Milltek SSXSB54 Exhaust is a resonated, non-valved T304L stainless steel, CNC mandrel bent, cat-back system. The Milltek exhaust begins after the factory downpipe with 76mm piping, flows through the resonated front pipe, continues back and splits to the two rear mufflers then exits through four 63.5mm unvalved exits to the quad burnt titanium 100mm GT exhaust tips with the Milltek logo. The Milltek exhaust improves power and response and gives a deeper more aggressive sound.

Founded in 1983, Milltek Sport produces high quality 304 stainless steel exhausts for the worlds finest vehicles. Headquartered in the UK with a development and testing center at the iconic Nürburgring, Germany, Milltek designs, develops and tests their range of exhaust systems in-house using state of the art equipment, such as the latest All Electrical CNC Mandrel Tube Benders and Faro 3D Laser Scanners.
