Hey Guys,

Been a long time since I been on the forum and playing with Mercedes again. Both of my friends just finished up their CLS 550s. The black car in the picture is a CLS550 with Speedriven Downpipes and Tune. The Grey car is 550 again with just Speedriven Tune alone. We will most likely run both cars on 100 oct. Tomorrow should be an ok day as far as temps go but I will update tomorrow. Both cars on street tires with 20s. We are trying to find out how fast and what kind of 60s we will be hitting and also the difference on the downpipes vs no downpipes. Car with the downpipes is running catless pipes.

Here are pictures of both cars

Tune Only Car

Let us know the results.
Great looking cars.
When I did the before and after dynos for the downpipe, I barely saw a result. The best difference was about 10 to 15 whp.

We ran the cars a few times could not get the downpipe car down the track more than 4 times so I think there is room there. I will post slips today or tomorrow.

The Tune only car went 12.450
The Tune and Downpipe car went 12.417

60ft times were terrible I will post time slips. Cars can def go 12.3 or faster I believe.

Awesome stuff, Kamil. What were 60'? 1.8?

You guys need to get those 60's down and the cars will be well into the 11s.

Let me know next time you guys go, I would love to run my CLS stock before letting Marcin/Spreedriven work his magic on my car.
