About an hour to install. 3inch pipe is used. No drone from being catless. Bungs for o2's are welded in oem location. We can add more bungs for data logging if wanted.

Only 20hp? Is that with or without the cats? Is that on an otherwise stock car? For downpipes, isn't it correct to say you'll gain x% over current WHP? It's not really a power adder, right? More like a power loss preventionerererer.
I always thought 7-8% was an average number for gains. No clue where I got that number from, that's just what I was taught growing up. Or, that's how my jacked up brain is remembering it, anyways. Could be totally wrong....

Been considering downpipes for my 05 SL65 and have done some reading on them. I understand there's 4 different downpipe construction methods; the difference appears to be how wastegate gases are managed (pls correct me if i'm wrong). The 4 methods are Blank plate, Bellmouth, Split Bellmouth, and, Divorced or Twin Dump. Which method has Speedriven used?

I have been debating whether to buy pipes, or just the flanges and make my own. Near as I can tell, these downpipes are just pipes. These turbos are internally wastegated, so exhaust is wastegated directly into the downpipe...

I think you might have researched import downpipes or others. These cars turbo's and downpipes work differently. On mercedes the exhaust mixes in the turbo housing and then goes down to a vband clamp where the downpipe starts.

Thanks ttboost! Appreciate the info...
Speedriven1, in addition to the pretty pics of shiny pipes and flanges, I'd still like to see the business end of the pipe(s). I think you understand that if I'm about to invest >$1500 I, like ttboost, would like to be "well [or better] informed."
Thanks in advance...

I didn't mean to be negative towards you, just like the fact that he did some research. I will try to get pics of full downpipes off the car.

I was thinking about catless pipes myself , but in asking around it seems i get the same answer that its really not needed and it will make the car stink ..LOL
I wanted them to get a little bit better sound from the car.
Some people swear the car sounds better some say the turbos eat up the sound.
My guess is the cats also eat up some sound so down pipes would change the sound a tad.
My local shop says remove the mufflers , others say the cats are the bottleneck mufflers are free flow
So I'm at the point where ya id like to have them from a mod stand point but will i really notice 20 to 30hp ? by the time that 30 gets from crank to wheel its now what 19ish just a guess. Will my *** dyno really feel it that i can say it was worth the trouble.
Then comes the other fact of selling the car...If i sell it to somebody from out of state and in good faith i have to tell them the car has no cats and will not pass inspection or i just need to put the cats back in to sell the car..
Then the person buying the car is like well no cats means the car was raced or beat on etc etc. Lets face it any one buying a car knows we only remove cats for one reason So I'm still tossing it around.
I want TTboost to get them first and report back

Marcin has machined the fittings necessary to do this in your own garage if you are that type of person. He also mentioned the install to take roughly 1 hour. I'd almost bet there is no cutting or welding and its designed to replace the stock section and reconnect with the proper hardware. This is what makes it attractive when you are concerned about resale and opinions of new buyers. It can be simply reversed if you choose, like other bolt ons. Also its being offered with and without cats. As already mentioned the 200 cell hi-flow cats will have little to no difference in power and sound its for you to determine if you will have issues with your use and with state inspections. Lastly I think Marcin is trying to be conservative with power figures, but its been mentioned that its more of a percentage increase. Logically thinking the larger downpipes should allow for the turbos to maintain boost in the higher RPMs and maybe even spool a bit faster with less resistance on exhaust gas exit. That being said the peak gain of power isn't the only advantage you should see.
I am very interested and this will end up being on my things to do list come spring.

You are putting way too much thought into this and missing some of the key facts mentioned above. Hopefully my cliff notes will make it easier to understand.

We do try to make all our product reverse able. The benefits are very noticeable especially with mods.

If the car already has an ECU tune is it necessary to reflash or dyno tune afterwards or will the computer just compensate for the change? I'm not looking to squeeze every last bit of power out of it but I do like to hold the pedal down for a while every so often. I'm just looking to make sure things remain safe.

I'm more curious about the sound..ie, how much louder? My car already has no mufflers, ONLY stock cats, so going catless would likely be considerably louder. Will I hear more turbo whistle, or drone or....? I would definitely buy the catless ones, as I already have no mufflers. And if it is only an hour job, putting my stock catted DP's back on (for whatever reason) is nothing...I've already dyno'd my car, so I could easily check the delta.
Oh yeah...how much better do the "Speedriven" cats flow than stock?

The sound wont be noticeable all low rpms/cruising, you only here an effect when the car is pushed. The turbo will be louder. There is no drone that we have noticed. The cats are not our's, we do use vibrant high flow cats, which are very efficient and don't limit flow

Probably not an awful lot of pics of this out there to reference, so I'll share mine. SL600 exhaust... With no mufflers of course.
