Finally my new downpipes with race cats (200Cel) is at my car...
.
I made a good deal because it took 4-5 hours to change them and I paid about 250 USD for that work.
First impression is that the engine responds much faster and at same time the turbos spool up quicker.. A little more sound also but not to much.
Because I let them install them at the workshop they install ugly clamps at the wraps so I'm gone change them.
Engine certainly got more power now.May be 20-30 hp?
Here few pictures about old and new ones.

I installed my down pipes myself. I can tell you it was a major PITA. If I could have got someone to install them at that price I would have gladly paid! Mine are catless and they are pretty loud. Can easily hear the turbo's and waste gates now. With the window's up it's not too noticeable. My neighbors are not too happy with me right now. When I start up in the morning it is really loud.

Mine is loud also. I want to do some track events, a lot of which have sound restrictions so I think I will go down the electric cutout route with some small high flow mufflers in the rear section.

The biggest change happened when I installed the CAI. I can hear smal whistle and when the turbos spoling up.
. When I had Scorpions the sound was higher than now.
Honestly, If I compare the CAI and Downpipes (with cats) the CAI made a greater impression on me than the cats / downpipes! I mean both did noticeable difference at power but the CAI more.

I have send them several e-mails and also ask what kind of product they recommend to use?
I have send them engine room pictures also... but now answers.
Only one "Rotating answer".... I'm angry.
Next I'm gone call their boss also and would say a few selected words. There are sitting paying people in customer service and do nothing!!!!They have a dealer in Germany also.... no answers!!!
Here is what "Steve" answer me from Heat shields products.
It’s a simple matter of airflow. When the air is flowing, the air will still heat up, just not as much as when the air is not flowing as much through the engine compartment. The image provides does not give us a good enough view to properly asses. Generally speaking if you shield the pipes after the intercooler it helps quite a big, you can also shield the pipes pre-intercooler. That does also seem to help a little bit.

Made from pulverized volcanic rock then strained into a fiber material, Titanium Turbo Shields can withstand direct heat up to 1800 F and 2500 F radiant heat. This means retaining more heat in the turbine and less damaging underhood heat. The result is a cooler air intake temperature and a boost in horsepower!

I was asking about those and the heat shield panels from the same company to try to keep the heat lower in the engine bay and the comment didn't go over well. I never understood why there wasn't more heat shielding around the exhaust on these.

Heatshield products
Finally answers from Heatshield products.... (Blown was right)
I have also ask if I do the CAI at silicon tube? .
We recommend our Thermaflect Sleeve ( http://www.heatshieldproducts.com/au...maflect-sleeve ) for the cold air intakes. If you have pipes, silicone hoses that change size, then we suggest you use our Thermaflect Tape ( http://www.heatshieldproducts.com/au...ermaflect-tape ). Both require minimum of 1 inch of airspace from the heat source.
I'm still waiting what they recommend under the coolers.
PS. They are very slow to respond

Can you tell us what your best time is at 1/4 mile?
We are still waiting for that info.....
All the rest of us always tell you everything openly what we are doing/made etc., but you have not yet said it?
Its not fair...

That's worse than stock. Something is wrong with your car. Have you dynoed it yet? http://www.caranddriver.com/reviews/...trumented-test
Here is what Car and Driver did with a stock SL600
PERFORMANCE RATINGS:
Zero to 60 mph: 3.6 sec
Zero to 100 mph: .8.6 sec
Zero to 120 mph: .11.9 sec
Street start, 5-60 mph: 4.5 sec
Standing 1/4-mile: 11.9 sec @ 120 mph

& obvious those huge dog bowls wouldn't be any good w/hooking a decent 60' but still ALL your Trap speeds are junk... Betting your Tune's extremely rich beyond CAI problems..

Are you trying to run 20" wheels and tires on your SL? Drop down to some lightweight 18's and it will feel like you gained a bunch of power....... which you would.

You could also have a failing intercooler pump, air trapped in your intercooler system, poor ecu tune given your mods. Dyno test with some data logging should tell you the issue.

I now what the probleem is... Far to slippery! I need 90% more grip. I must have ESP on al the way.. : ). I run with old Camaro turbo. He had 11,5 and I lose directly from the line. He had at 60feet 1,5 sek but I catch him the last 1/8 mile and we have nearly the same top speed 117,5 mph. So honestly the power is there ... : ). My race start after the first 1/8 mile.: ). It was at airfield track.

So what kind of tires must I buy.?
w/your mod list you should be Trapping 125-126 mph @ the very least in the high 10's w/good DA etc.. What was the DA & Ambient track temps? You're running near Stock trap speeds..My bud Clayton Benzorama here, ran my EXACT OE Dyno tune w/spdrvn TCU on otherwise bone STOCK SL600 @ 11.0x @ 126-127 mph on stock 18"s w/dragtires on rear, though he had big heavy 20"s up front.. IE No other perf mods... Your SL is way, way, way, down on hp... And again for stubborn ears DragTires do NOT increase Trap speeds, they make your car quicker, w/slower Traps. It will launch harder w/slightly slower overall trap. You also need to ditch the big heavy 20"s in front they're killing speed/too by adding massive drag resistance etc Unsprung weight advantages can add up to 2-4mph & drop 2-4 tenths off your final 1/4 etc..
Put snow chains on or buy some w/ice spikes lol...

It's not your ONLY problem, in reality your Trap Speed will actually go DOWN w/better 60' though you def will run quicker just not faster. 117 mph is telling you your rigs wayyy down on hp/tq but believe what you will Prof You should be Trapping 125-126 mph you're running near Stock trap speeds..

...Im not worried about the power.... Its there.: ). Its def. there ...100% sure about that. Everyone laught to me at my 4 races becuase they saw when my car spinn three times at 1/4 mile when I hade ESP off.... : ).
I'm really stupid when I even tried with this tires.: )
