SL55/63/65/R230 AMG: SL65 Catless Downpipes




LSD I'm hoping gets here Friday seeing we had to special order the SL65 LSD from Quaife last Friday. As for toe links Renntech never got back to me if I need their cambers or not for there toe links, I'll spend $1300 for toe links but $1100 for cambers
but their is a vendor in the UK that I bought my Carlsson Rims that have a pair of Evosport toe links. Also I'm glad I have a high flow muffler and dual exhaust cut outs. The high flow mufflers make it sound nice with a growl but not that loud. But when the cut outs are open holy ****. Its really loud and nice but I live in the DC area and work a lot in NYC and both area's have quiet zones which can have me ticketed which will give cops another excuse to ticket me by not having front plates. But if you guys are wondering how loud no muffler and cats are, the answer is very loud
Side note: Carbon Fiber trim came in last Friday, Installed it today and the Black/Charcoal leather with Carbon Fiber Trim looks a lot sexier now then the wood that clashed with the leather
cutouts bypassing the exhaust should make a BIG difference in power. I used to have an older 2001 Grand Prix GTP witha turbo swap. I put in boost activated cutouts and gained 35 WHP. That was only a 400 WHP car. I would think 50 WHP on these cars. Turbos really dont like exhaust restrictions. I also remember how much faster the turbos spooled with cutout. My cutouts were boost activated so you could cruise around totally closed and they would start to open at 5-6 PSI and fully open at 15 PSI. Was pretty trick. Not sure if they are even around anymore.

From Open House ECU Tune of 563.53 to......

To 634.81!!!

We were getting stumped on what was going on and fuel air looked good, so Jerry recommend removing the OEM air boxes. Turns out when you have 3 inch cat less the air boxes won't cut it. So I'm having custom intakes built next week. Can't wait to see when air is being forced into the turbos.
Once I get the intakes in I'll do another run on 93 Octane. Then I'll add a trunk tank add it with ice and do a run with Q16 fuel

Also by doing so it looks like I have enough room to have a Quad top intercooler like the ones Brabus does So I'm doing that too. Can't wait to see when the turbos gets help from intakes and sucks up more air
I was going to do downpipes in about 3 weeks but now I'm unsure if i want to unless i do aftermarket air box. Im running Bmc filters right now.
How does the AFR do with the tune? was the car able to trim itself after the pipes and air box removed or did you guys have to add fuel to the tune?

Building the intake is much cheaper than spending 5 grand on the Renntech air boxes and having the intakes mounted at the front, I should be getting some good cold air coming in esp at higher speeds. Plus with no air boxes I can 2x my coolant capacity on my top mount inter coolers
I mean if your thinking about intakes you can just wait till next week till EC/DC builds my intakes. Assuming the pipping gets in before Wednesday. If it does looks like all I'll need then is tune it for Q16 before MIR that Saturday
I hear some guys run 60% and 80%
Eurocharged Heat Exchanger
CM30 Johnson Pump
Eurocharged ECU/TCU
Custom 3 Inch Mandrel Bent Exhaust:
Catless Downpipes
H Pipe
Dual Electric Exhaust Cutoffs
High Flow Mufflers
Carlsson 19 Inch Ultra Light Rims
With the cutouts open and closed it didn't really make a difference I was still running consistent 630+ rwhp
What I have lined up now is the following:
Quaife LSD (Waiting to be installed)
Lowering Links (Waiting to installed)
Custom Dual Ram Cold Air Intakes (Ordering parts)
Trunk Tank (Ordering parts)
Quad Top Mount Intercoolers (Ordering parts)
Evosport Toe Links (Ordering parts)
Also I'm trying to see if I have enough room to 2x stack the Heat Exchanger in the front
I'm debating if I should do a larger wheel on my OEM turbo to add a little more power while I stock pile my funds for a 1000+ HP build after I do my Black Series Kit

If you go on the Eurocharged DC Facebook page they did there last one on an F10 M5, and I'm having them build it like that in front of the radiator.

As for the intake set up it will be cones in the front of the radiator, then piping all the way to the turbos. This should get good cold air coming to the Turbos and improve the car esp at high speeds.
As for TQ reading the Dyno Jet can't read our TQ levels for some reason but we are looking for a dyno around the area that can. We think tho the TQ has to be 800ish rwhp
Maybe I can paint my brake calibers pretty up my car more on Tuesday and show off my new Carbon Fiber Interior on Saturday lol

Is there any benefit if the air boxes can't flow enough? I was feeling real good when i pulled the oem filters out and replaced with Bmc they seemed like they could flow something good.
I was running with the Air box best I got was 540ish and it would run all over the place from 480 to 510 to 520 literally the air box chokes up the cars flow.
The moment we took out the air box I was getting consistent 630 rwhp
