AMGfan SL65 Update
1. Installed Evosport toe links
2. Cat delete
Pics of the toe links forthcoming...the squirly feeling under heavy load is no longer there...its just hit the accelerator and go whereas before the back end felt really unsteady. I have the Renntech toe links on my E55 and it does the same job and I would advise this as a good buy. I just feel more confident with the toe links on...the AMG's and all their torque really need the toe links.
The cat delete:
a. It sounds a lot meaner...darth maul speaks!
b. My buttacceleromator feels a strong change but I need to compare that to a real dyno graph or I'll just wait until the temps get cooler and take it to my 1/4 mile track and see the numbers there.

Cat deleted due to no emissions testing in FL anymore, right? Wonder if race cat (which may pass Houston emissions) would perform similar? I'll have to look into those toe links. How much were the parts/install if you don't mind?
Always love the updates - keep them coming! Such a sick SL65!

Toe links are definitely a great mod. I have been wanting to get this done on my car. It should be standard on all AMGs along with LSD or at least offered in the 030 performance pkg. Can't wait to here the sound clip. I love the sound of the smooth V12 monster.

We had the cats on my car replaced with straight pipes too!
And also the last silencors/mufflors back there.
So now I have it straight piped aaaall the way!
The car sounds just great!
And we dynoed it before, and after, on that same day.
But the sad thing is that the dyno showed no HP-gain after this mod!
As you stated, it sounds veeery nice!
I would sooo keep this mod, even if I lost a few horses on the way!

how were there no gains? even a decent flowing cat is restrictive, and I have to assume it gave your turbos better spool up. the last turbo car that I threw a flow through down pipe on gained around 25 hp. I'm also interested to hear a sound clip
I would also like to hear what you think of your car with the new links, I would like to hear if it is worth the dough or if it is snake oil

i had been considering the toe links and a Renntech LSD for my build but a close friend (and very knowledgable car superfreak) told me that i should save my money as i wouldn't really get much benefit unless i was gonna be tracking the car. most of my hard driving is on the highway with some mountain twisties and of course the traffic light launches.
if you don't mind, i'd like to hear your detailed impressions now that you have them in these types of scenarios. what did you mean by the back end felt unsteady, etc?

buongiorno AMGfan,
i had been considering the toe links and a Renntech LSD for my build but a close friend (and very knowledgable car superfreak) told me that i should save my money as i wouldn't really get much benefit unless i was gonna be tracking the car. most of my hard driving is on the highway with some mountain twisties and of course the traffic light launches.

Ours or Renntech - you WILL see a huge improvement - straight line and cornering.
Just think, you drive away from stop lights how many times a day?
Thanks

cool. can you describe specifically what i'll feel different in the straights and corners vs stock car? will the ride be harsher, etc? i don't doubt you, i'm genuinely curious.

I'm subscribed as well. would like to hear more about the toe links...Brad can you shed some insight as to how they work and what are the performance gains from them, on an application for SL55 which is say dragged a few days a year on drag radials and street driven the rest of the time...thanks

very simply, they will significantly limit the amount of deflection of the rear arms. This prevents the car from going from your static toe to extreme toe-out, which creates the "wiggle" or "squirly" feeling under hard acceleration (straight or turning).
In the turns, the toe-out change is even more potentially troublesome as it will change instantly and cause snap over-steer (the rear steps out). BMW e36 and e46 do this as well, but the fix is much easier with RTAB shims.
Thanks

Now I just hit the accelerator and the back end feels more planted and momentum is going forward rather than the side to side feel I got at WOT. I still lose traction just because of all the torque but the chassis/rear suspension feels more in unison.

Thanks Brad...for those of you who don't know Brad, Simon, et al and myself all raced in the same series with BMW. These guys have been making parts forever... in fact Brad and his Dad had one of the first M3 Ligthweights campaigned when our cars were still in the HP race class. Good group of racers out there on the West coast.
Brad...how's Holder doing? You guys built that monster e46 widebody CM car for him....whatever happened with that car? What projects have been keeping you all busy lately?

And lesser restriction than a straight pipe isn't invented yet, right..?
A sound clip was attached there. But something happend with that link. Here it comes again..;

Did the cat free exhaust move your power band any? I would hope it fattens out the lower RPM's, but I was wrong on my making more power assumption too.

But if it gave some more power at mid range or somewhere else, I don't know.
I can ask him to print it out, and mail it to me.
Then I can read that out...

maybe this is a 600 vs 65 thing and the less restrictive factory exhaust frees up stuff more on the 65 than the 600. I still think I might go with the dual 3" with hi-flow cats
