How much power can be gained from these mods together?

Also, is it better to go with Kleemann's tuning or go with one of the other tuners, like EC or OE? I want it to be safe and it is my daily driver. I also want to be able to pass emissions, too, and I hear only Kleemann can modify the ECU with their headers to pass emissions easily.


Any feedback would be appreciated. Thank you.

I want to say my CLS55 with this was @470

I believe tgoss had this setup on his e55 and he put down something like 48xwhp and 6xxwtq!

Ya, i was thinking my CLS was 479.
I still had CATS and a Meisterschaft exhaust.

I had this setup while I owned Tal's car. It is beast!! Car ran very well and made a ton of power. Wish I had ran it at the track before selling it.

The CLS pulled like a raped ape as well with this package.

iv seen a dyno of a sl55 with these mods plus a bigger tb put down 52xwhp.

Ill let you know soon as Im looking for a 168 to drop down too

edit 522whp

The headers were already on the CLS. So tell me something, if the CATs do not work with these headers, what do you put in place of them? How loud is it with headers and no CATs? Mine had factory cats welded in but it was not pretty.

I have the primary cats deleted with the kleemann down pipes and the rest of the car is stock.

It sounds a little deeper than stock and 90% of the people that hear my car think its bone stock sounding.

emoving

Ok, so did you cut the primary cats out and weld it back together?

skratch77

We have no choice to keep the first cats with there headers,the kit comes with down pipes that you have to cut and weld to the stock section where the first set of cats are.

I will look for some pics from under my car and post em up.

skratch77

here is what Im talking about.You can see there down pipe bolts right onto there headers but you need to weld it to the stock section where the cats connected to once you cut them out.

Basically eliminating primary cats w welded downpipe provided by klemann

It just seems the would make something that looks and works a little better together. I know its the bottom of the car, but I really am to **** to have it look like Frankenstein.

skratch77

In person it looks 10x better,that was with a crappy old cell phone,if it wasnt for the shinny stainless steel you would think my car came like this stock.

the car looks stock except for maybe 6 inches of shinny headers and those 6 inches is where my 600rwt 530whp came from lol.

I would take that over any other setup anyday.If your super **** just have the shop keep your stock cats but what the heck is the point of that?

skratch77

here is an sl55 thats a little different but its basically done the same way.looks stock except a few inches where the cats were.

Stock cats are the bottle neck some guys put race cats in for primaries . I plan on running secondary only and send ecu to Cory to fix cel/not ready to pass emissions.

11.4 with Dr's

On the computer it looks much better then on my DROID.

I went from stock to this setup and it was incredible. Klees dyno is weird as it tries to calculate your crank hp. Mine went from 480 to 600 crank on their dyno.

Butt dyno was dramatic. You'll LOVE it!!!

That first drive is magic!

Baronet1

Nice.

What kind of traps will a car with these mods do? 122? more?

6xx rwtq with Kleemann's: 168, headers, and tuning?

This makes me ecstatic to get the mods in!

EDIT: I dyno'd once on a Mustang/heartbreaker and made 392/458 stock so this will be quite a jump in power.
