RennTech has developed this power packed yet stylistically subtle package specifically for the S550 sedan. RennTech achieved this with just a few modifications that make a vast improvement in the overall presence and performance of the S-Class in stock trim.
The tasteful exterior upgrades start off in the rear with a pre-preg carbon fiber rear decklid spoiler, designed in-house at RennTech and manufactured in the USA. Stainless Steel Sport Mufflers make sure that the S 550 turns heads before you can even see it.
Electronic actuated valves eliminate unwanted loud exhaust noise while driving in low RPM ranges. RennTech valved sport muffler utilize the electronic OEM actuators. All exhaust systems are designed and manufactured at the RennTech HQ in Stuart, FL. Optional RennTech Deep Monolite Wheels are available in a 10-, 10.2- and 16-spoke design with a 21" front and 22" rear fitment. You can choose between three different finishes: Brushed Aluminum, Gunmetal or Titanium.
The RennTech S550 tune unleashes the true potential of the 4.7L V8 Biturbo with power figures boosted up to 540 horsepower and 705lb-ft of torque. Throttle response is also greatly improved, transforming the standard S 550 sedan into the quintessential perfect blend of stately executive class and AMG-esque performance. With a minimalistic yet effective approach, RennTech has proven there is a void to be filled between the S550 and S63 variants.
