Racingline Turbo muffler delete for VAG MQB EVO EA888 Gen.4 (Garrett turbo)

Racingline Turbo Muffler Delete – VAG MQB EVO EA888 Gen.4 (Garrett turbo) – VWR160000

The Racingline Turbo Muffler Delete is a direct replacement for the factory turbo muffler, which restricts flow on the latest 2.0 TSI EA888 Gen.4 engines with a Garrett turbocharger. The factory plastic chamber is replaced by a precision-machined solid aluminium pipe and a larger silicone connecting hose, reducing the restriction at the turbocharger compressor outlet.

The factory muffler is fitted primarily to reduce noise in the engine bay. The disadvantage of this design is turbulence at the turbocharger air outlet, which can worsen boost response. The smoothly shaped flow path, developed using CFD analysis, allows less restricted airflow.

Operation

• replaces the original muffler with an internal diameter of 38 mm;
• the tapered aluminium pipe expands to a diameter of 53 mm;
• the included silicone connecting hose has an internal stepped transition for a 53 mm diameter;
• reduces turbulence at the turbocharger compressor outlet;
• improves boost response and throttle response;
• allows the turbocharger to be heard more clearly, including spool and air-release sounds.

Why the difference is noticeable

The standard muffler is mounted directly at the turbocharger compressor outlet, where smooth airflow is particularly important. Even a minor restriction can cause the turbocharger to work harder. The Racingline tapered replacement pipe keeps the air in a straight, uninterrupted flow path, allowing the turbocharger to establish boost more quickly and the engine to respond more directly to throttle input.

Expect a small but noticeable improvement in responsiveness, not a large increase in power. This is an improvement to the flow path and response, not a standalone power-increasing product.

The turbocharger will also sound more pronounced. Compressor noise becomes more audible, as does the sound of the diverter valve.

Construction

The replacement pipe is made from a single piece of solid aluminium and has an original-equipment-quality finish. The reinforced silicone hose is designed to withstand the pressures and temperatures of the EA888 Gen.4 turbocharger system without deforming. Installation is direct, using the original clamps and mounting points.

Important compatibility restriction

The product is not suitable for engines producing 300+ PS. It is intended for the 245 PS version of the 2.0 TSI EA888 Gen.4 with a Garrett turbocharger. If the vehicle has been software-upgraded beyond standard power or has a larger turbocharger with performance comparable to an IS38, this product is not suitable.

Installation

Installation is straightforward and can usually be completed with basic hand tools in less than one hour. The kit includes an aluminium replacement pipe and a silicone connecting hose. Remove the original muffler and secure the new parts using the existing clamps.

The Turbo Muffler Delete is a simple, precisely designed upgrade that removes a known restriction in the factory intake path of EA888 Gen.4 engines.

Suitable for: Audi A1 II (GB), Audi A3 IV (GY), Audi Q2 I (GA), Audi Q3 II (F3), Audi TT III (FV), Cupra Ateca I (KH7), Cupra Formentor I (KM7), Cupra Leon IV (KL1), Cupra Terramar I, SEAT Leon IV (KL1) / IV (KL8), Škoda Karoq I (NU7), Škoda Octavia IV (NX3) / IV (NX5) and 6 more (see the table below).
