Looking for more power and performance from your W216 CL550 Biturbo? With a high-performance exhaust and ECU tuning PKG from Speedriven you'll be making nearly 550 HP ... more than enough to go chasing down your neighbors' AMGs and Porsche Panameras!

Our W216 CL550 PKG includes a full down-pipe and cat-back exhaust system made from high-quality 304 stainless steel, Speedriven's advanced ECU software tuning, and a set of high-flow drop-in filters for $7000 plus installation. We also offer a billet aluminum transmission pan ($750, incl. trans. service, a $189 value) and an upgraded intercooler pump ($750) to keep things running reliably cool.

Here's the thing, though: we're selling a lot more through our webiste, lately, and customers are asking us for new installation instructions. To give them (you) a better DIY/local shop experience, we want to take our time and photograph each step of the installation process on all of the W221/W216 products Speedriven offers.

SO, if you're local, you can help us out. Drop off your W221 S550 or W216 CL550 with a 4.7 liter Biturbo engine at Speedriven for about a week, and we'll give you an absolutely smoking deal on every high-performance goodie we can throw at the car.

PM me for details. Ideally we'd have the car the week of April 25-29 at our shop in Palatine, IL. Thanks!!
