Custom sonny long tube headers stainless steel.
Custom sonny built exhaust system including genuine amg resonator + rear muffler.






100cell stainless high flow cats.
3inch full system including custom sonny xpipe.
Out of supersprint headers, kleemann, renntech, sonny headers I loved the best he showed me all of them and for the price I paid it was worth the power I got.
The shorty headers gave 9hp at wheels,
This exhaust system gave me nearly 40whp believe it or not but will be posting dyno results up of everything when I do get my car back Tuesday.
If you do live in Australia I would recommend this to anyone.

How do people generally feel about high flow cats? How much do they flow over regular cats and how much less than no cats at all?

faz492

a lot over the restricted 500cells in the benz, I may be wrong if I am someone correct me, in the 100cell the honeycomb in the cat have less cells and the cell chambers are bigger thus exhaust gasses coming out freely than 500cell with the chambers very small and a lot more of them. I think that's how the concept works.

got my dyno results back and pick up my car tomorrow >

I'd like to get more input from people but where did you get the 100 cell stainless high flow cats?

faz492

Autowerks Automotive where I took my car ordered some highflow 100cell cats.
I can find out what brand he used on my amg if you like.

bokka 100cell sports cats I have in my ride.
Oh my god let me tell you something.... the car is brutal with the mods haha

Sal Collaziano

Sure, if you would I'd appreciate it...

Sal Collaziano

Would you happen to have any videos of what your exhaust sounds like? Do you have the secondary cats connected or no?

faz492

bokka 100cell sports cats I have in my ride.
E63 amg doesn't come with secondary cats.
I can post a video up tonight or tomorrow.
In the cabin and cruising speed its quiet as a mouse but when you plant the car omg it roars at ya.

HPMan

Looks good. Any before and after dyno graphs? Please post.

Sal Collaziano

Thank you. I'd love to see the video.

Need4Speed

Very nice Post a Video I care to see how it sounds

the Meisterschaft system for the E63 sounds insane in person I've had the pleasure of hearing it

man thats some *****in art under there

Throttle opening stock = 55% @ 1500rpm, 47% rest of the way
Throttle opening after tune = 90% constant.
After Torque = 784.4NM
Stock torque =603.5NM
All up gains I got are 74whp from just two things, Autowerks Automotive are simply amazing when it comes to tuning and servicing.
329wkw = 441whp (end result with exhaust and tune) tune gave me 34whp!
304wkw = 407whp (with just full exhaust) made 40whp over stock!!
274wkw = 367whp (stock car dyno carbonio airboxs didn't make any more power than rows)

faz492

Needless to say the car went like a rocket, to bad I crashed it haha....

faz492

Have you done a dyno for your car to see how much power it makes?
I was wondering if the throttle body is worth buying from renntech for the power to $$ ratio it didn't seem that worth it for me but I may be wrong.

Sal Collaziano

...not yet... 11hp & 8 lb/ft - I don't know. I believe that's at the crank as well. Not at the wheels...
