Here are the results and some pictures of the long awaited Gintani Header back Exhaust for C63 AMG. After the last round of testing the car was flashed to stock, the exhaust installed, adaptations cleared with SDS, over 60 miles of driving with the exhaust and the factory stock tune prior to this dyno session.
The results are as follows for the attached Dynograph:

Stock Car Baseline - Orange
Removal of Charcoal filters and the addition of K&N Filters - Blue
Gintani Header back exhaust with stock tune - Pink
Gintani Header back exhaust with ECU tune - Red & Green

The feel of the car with just the addition of the exhaust is as good as a tuned car feels down low. The exhaust + OE Tuning tune = Awesome!!!
I may be biased as this is my own personal car, but I think this exhaust has the best sound of any of the hundreds of C63's I have seen and heard.

So the exhust picked up about 10hp over cat removal? I'm I reading that right? How much does the complete system weight? Looks good great job..

Looks great but do you have a pic of the tips? Or are they stock?

Interested in a resonator back solution to go with my MHP longtubes/3" mids..

Boost Gomez

What use would there be for a resonator back solution? The OEM mufflers are perfect.

GHAZAN

Will there be a mid section only with the Xpipe and dual resonators that connect just before the mufflers or is in one whole set? like akrapovic

More for sound experimentation....

Off topic But....
Gintani Should be a sponsor on MBWorld.

GHAZAN

this is the longest release for a exhaust ever

_AMG_

Patience is a virtue.

GHAZAN

my mom used to always tell me the same thing but i never understood her

Almost.....when Gintani released pics of their exhaust next to the OEM, the OEM had a nasty flat spot just past the resonator that will reduce flow.

Good question.

If such a setup was available, would it be a problem if part of the exhaust is 2 1/2" and the middle part is 3"?

This exhaust setup is really clean and obviously makes great power. But, if I were to install this exhaust, I would want to keep stock C63 mufflers.

GHAZAN

what is the size of this system to begin with? do we know?

They have alot of flat spots. One of the tips on the OEM system actually has a really big dent through it.

3" piping.

The stock C63 muffler has a very throaty sound. The Gintani Exhaust has a deep growl, but it is unlike anything I have ever heard on a C63. It sounds great.

That's because the stock cans have very little (if any) baffling and sound deadening material - they are a straight through design hence the raspy exhaust note that Alex hates so much and was the reason why he developed his own cans which sound much more "tuned". Personally I think the stock cans sound much better and more raw - to each his own.

I have seen the inside of the C63 exhaust and it is indeed a straight flow design. I personally love the sound of the stock muffler.

SonnyakaPig

I have heard it in person. Couple months ago, I think .

I like the smoothe sound of the Gintani exhaust, and I really admire the power it makes. But, I like the throatiness of the AMG system more.
