Generic:
The SPORTS LABEL from REMUS GmbH is a superior quality product due to numerous factors such as build quality, performance and sound!
Quality:
All SPORTS LABEL exhaust systems are made of aircraft quality 304 stainless steel inside and out. The canister is electro polished to ensure a lasting finish and some sections of the canister are covered with high endurance black ceramic paint to prevent damags and for better looks. Remus did not stop there, it offers one of the largest selection of tip designs which are of the highest quality on the market. They feature high grade 441 stainless steel. Why 441? It is more resistant to corrosion and surface rust than 304. The tips are also chrome plated to ensure a lasting shiny finish and moreover, they are resonated to ensure a drone free system.
Performance:
All SPORTS LABEL exhaust systems are engineered with performance in mind, they all feature straight through free flow designs to ensure as little resistance possible thus promoting great horsepower and torque gains. All of the SPORTS LABEL systems are tested for back pressure reduction and REMUS GmbH uses it's own roller type dynograph to ensure positive wheel power gains on most of the models.
Sound:
All REMUS exhaust systems, from the Wild Labels to the Racing systems, are tested in an industry exclusive sound chamber. This allows REMUS GmbH to fine tune every single exhaust produced in order to meet the expectations of our demanding customers. All SPORTS LABEL exhaust systems are TUV approved and are thus legal for road use in Europe*. The decibel level is very close to stock/OEM however the sound characteristics are altered to offer a deep and refined tone absent in the factory exhaust system.
Every SPORTS LABEL exhaust system features the following:
• Straight through free flow design
• TUV approved*
• Made from 304 stainless steel inside and out
• 441 Stainless steel chrome plated tips
• Vast selection of tips
• Lifetime unlimited mileage warranty
• Installed using factory mounting points
• Black ceramic coating for better look and to prevent surface damages
• Machine TIG welded and mandrel bent
• CNC machined
• Laser engraved REMUS logo
*unless noted otherwise under specific!
Please note: Delivery time is normally 2-3 weeks.
