The APR Turbo Muffler Pipe and Turbo Outlet Hose takes a multiple step approach to upgraded these components which results in a much larger and smoother airflow path than simply upgrading each component on its own. The turbo muffler is designed to soften sound from the turbocharger, taking away the sounds enthusiasts enjoy. We do away with this and in doing so we eliminate a restriction path that causes turbulence and reduces performance. The outlet of the muffler pipe has a cross sectional area 66% larger than stock. By upgrading both the hose and muffler pipe at the same time, we're able to dramatically increase the size of the system to match the size of the other hoses and pipes in the charge air system, just like on the higher output Golf R / S3 Models. Unlike some components on the market, the APR system retains the critical PCV vent path on the muffler pipe for necessary for proper engine operation. Because a critical seal is not necessary due to the need for a PCV path, the muffler pipe is created from a solid piece of billet aluminum with a satin black finish and no need for extra gaskets.
Attached to the turbo muffler pipe is the APR Turbo Outlet Hose, which replaces the factory rubber hose and worm-gear clamps with a high quality multi-ply silicone hose and strong Clampco T-bolt clamps. The hose has a cross sectional area 66% larger than stock thanks to upgrading both the turbo muffler pipe and outlet hose at the same time. The interior of the hose is smooth and lined with a fluorosilicone material designed to resist oil degradation and extend component life. EZ-Flow stepped lips within the hose allows for a smooth connection from hose to pipe
