Awesome vid bro with lots of fly-by action! 
Wow, those Supersprint headers definitely brings out the Beast in the SLS. It just screams at high RPMs. Can't imagine what it sounds like in person or even in the cabin. Thanks for posting!
I put headphones on for this one. Yeah, you owe me some eardrums dude!

Sorry guys for not posting the post dyno sheets yet. we were busy this past week. We tried to dyno it for the past two days, but it was raining and the roads were not suitable for driving. Hopefully the weather clears up and I will try to dyno it for you all by tommorrow

Ok guys, We finally got some dyno results for you all(ECU tune + SuperSprint system). Again, this test was made on the same dynodynamics dyno that we used for the pre dyno graphs(ECU TUNE ONLY). This type of dyno is known to give low readings. In particular, our dyno gave inaccurate results. You can see form the graph that the fuel cut off points were at around 6400 RPM, which is even less than our pre dyno fuel cut. This is defenitley not giving us any info on the peak horsepower gained which comes right before the fuel cut. Our SLS revs at around 7600 RPM. We still managed to get 40HP and 45 lb/ft over our last dyno. I will take it to a more accurate dyno, possibly Dyno Maha, when I travel to the UAE and I will post the results for you all. The SLS on the street is a pure racing machine. We were able to murder a brabus SLS and ran it like it wasnt even racing, a 2011 PDK 911 turbo S, and a modded LP640. Its just amazing how it accelerates right now. Here are the graphs, I included the previous pre dyno graphs as well:
at the Crank:
At the wheel:
Results of the Supersprint Exhust System:
Results-Crank:
HP: 614.9-575 = 40HP
Torque: 565-520= 45 LB/ft~61NM
Results-Wheel:
HP: 507.4-474= 33HP
Torque: 569-525= 44 LB/ft ~ 59NM
I'm pretty sure that if the fuel cut off point ended later than 6400 RPM, we would have seen more Peak HP. The Dyno isnt very accurate and isnt calibrated regularly. I want to note that we gained 61NM of torque in mid range, which is really impressive. the motor is now making 565LB/ft which is 766NM.

Ok guys I want to note something. I was looking at the dyno graph in detail. forgetting about HP numbers and peak horsepower, I have come to find this, and makes more sense:
At the Crank:
At the Wheels:
If you look at the pre and post graph and look at the gains carefully within the same RPM range, you will find that at the crank there was a gain of 51-60 HP increase.
I was actually more surprised at the gains to the wheels, where there was a range from 37-50HP to the wheels
Most of the gains come at mid-range power. Therefore, I have come to notice that when comparing these results with our previuos dyno results the gains are actually 60HP at the crank and 50HP at the wheels
. the peak horsepower of the post dyno cuts off is @ 6400RPM which is way before the 7600 RPM limit that we have on our SLS and before the pre dyno test we did @ 6500 RPM. Therefore, I will leave it to you to find out what the actual peak horsepower really is on my motor until i take it to a more accurate dyno later this year

Thanks moe. If you look at the analysis I made above. The gains are actullay 60HP and 61NM at the crank and 50HP and 59NM to the wheels. The tuner I used is a well known German tuner that has been breaking records in europe for this platform. PM me if you want to know with whom
, while stock the cut-off line is 6,850 rpm. With my tune I see it in front of my eyes that the cut-off line is beyond 7,000 rpm. I hope to take it to UAE someday to put it on a DynoMaha
