Renntech

RENNtech has become the premier Mercedes-Benz specialist and Hartmut Feyhl himself is regarded by many as USA’s foremost authority in Mercedes tuning. His vast experience comes from 12 years spent at AMG Germany before serving as the North American division’s Technical Director. Prior to the tuning company’s merger with Mercedes-Benz in 1999, by the request of AMG Germany, Feyhl branched out on his own to start RENNtech and service the existing AMG North America customers.

Performance without compromise. This is the foundation upon which we have built our reputation. Established in 1989 by Hartmut Feyhl, RENNtech has evolved and grown from servicing AMG’s customers into the foremost authority on tuning and customizing AMGs and Mercedes-Benz. RENNtech also offers tuning solutions for Porsche, Audi, and Bentley vehicles, along with other European luxury cars.

 

Renntech produces and carries a wide range of products for many modules of the following European makes:

RENNtech Sport Mufflers are made out of T-304 stainless steel (SS) and 100% handcrafted in the USA.
This exhaust system is rigorously tested to remove any unwanted resonances in the cabin to deliver a deep sound that keeps with the character of a luxury performance vehicle. Our mufflers with 2 3/4 inch diameter tubing offer lighter weight than the stock exhaust and improve performance by reducing exhaust backpressure, increasing exhaust gas flow and cylinder scavenging.
