The CTS Turbo FSI (K03) Turbo Outlet Pipe (TOP) is designed to replace the narrow 'pancake' pipe that comes as factory equipment on your K03 turbo equipped FSI. Our Turbo Outlet Pipe features 2.25" diameter aluminium tube for optimized flow. The CNC machined billet mating flange makes connecting this TOP to your FMIC literally a snap. The billet anodized turbo to TOP connector, 2.25" coupler and premium clamps top this package off. If you're looking for a simple bolt on modification that will optimize flow and power then look no further.
