Racing Line’s Tapered Turbo Muffler Delete & Silicone Joiner kit for Golf mk 8 GTI and all other EA888 gen 4 245PS engines makes s a valuable contribution to your car's smooth breathing - banish the disruptive airflow of the stock part and hear your turbo working at last! This Tapered Turbo Muffler Delete for Golf mk 8 GTI and all the other MQB ‘EVO’ cars using the 2.0 TSI EA888.4 245ps engine is a sleek single billet design combined with a larger diameter silicone joiner hose which replaces the restrictive, power-robbing compressor outlet with a smooth, turbulence free air path exiting the turbo. The standard part is located on the outlet of the turbo compressor to reduce engine bay acoustics, but adds in disruptive turbulence to the airflow right where you don't want it. Whilst the OEM part is a 38mm inner diameter throughout, the Racing Line tapered design enlarges that right up to 53mm, joining perfectly with the smooth 53mm, internally-stepped silicone hose. By replacing the standard part with the tapered Turbo Muffler Delete and Silicone Hose, you’ll replace this unwanted restriction with a smooth CFD-developed uninterrupted air path. The result: noticeably better boost response giving a little more power and throttle reaction, all the while being able to actually hear your turbo working at last! The perfect combination with Racing Line’s R600 EVO air intake and Turbo Inlet System for this 245ps Garrett-turbo engine.
