Mercedes’ latest SL550 is powered by a high-tech, 4.7 liter biturbo V8 engine that makes 429 HP and 516 lb-ft of torque. That’s enough to make the SL550 a thrilling performer, but it’s a refined performer, too. Some might even say that the smooth V8 and quiet Mercedes-Benz factory exhaust system conspire to make the car a little too refined.
Besides, that 429 HP is just a sample of what the SL550 engine is capable of!
Speedriven addresses both concerns about the SL550 with a series of high-performance upgrades that crank the 4.7 liter V8 all the way up to 550 HP and 620 lb-ft of torque with the help of a lightweight, free-flowing Speedriven sport* exhaust that improves power, reduces weight, and greatly improves the SL550’s exhaust note.

For this example, Speedriven is keeping things cool with an intercooler pump upgrade and one of the firm’s billet aluminum transmission pans, which increase fluid capacity by 2 liters while providing superior cooling compared to the factory pan. Reproducing one for yourself will run you $7650 (plus installation and a $180 transmission service to make sure everything is operating as it should be). For more information, contact Speedriven or your local Speedriven dealer.
