Close-ups of the cats and preparation of the final install:

 

I have to leave for work now, but here is a little teaser of the tips that Mark recommended to me. The whole exhaust is a 3" piping, including the X. I did not want a pronounced loud car, but a good flowing exhaust that lets the turbo breathe out so we opted for a slight neckdown with these tips.

The neckdown should reduce the loudness to some degree and it is far away of the turbos so the contribution to backpressure is minimal.

All welds of the tips are ported and their flow should be optimal. I also find that they look awesome.

 

This bumper and the rear decklid are one of the highlights that Gemballa has designed. Much of the Gemballa stuff was over the top, but this 996 work was pretty good.

I have worked on the front bumper last year and it looks slightly different now. Changed the mesh to a finer one and took the plastic looking air guide out and exchanged it with the carbon part of the GT2.

Uwe Gemballa played games with people you even better don't know and paid with his life.

 

Looking good Andreas

 

Mark what do you think of those cats for flow?

 

Very nice!

 

The second part of this installation was a bit thrilling, because we could not know beforehand if the exhaust will fit the car.

There is a few thousand miles between Mark and me and he had no chance to fit the exhaust exactly to my car but we had to assume that my car, which has Gemballa aftermarket headers, will behave just like a standard 996 TT.

Fortunately the exhaust did fit as if it was perfectly built for my car. There was absolutely no pressure or tension. Everything fits to the point. Great job Mark.

I will write up some more information later. Here are the installation pictures:

HI,What was the reason you have louvered cores in the mufflers instead of straight perforated ones?? For sound/quieter? Thanks

 

Finished and I am really, really happy to have such a beautiful exhaust. This is a peace of art to me.

I just put the tips on to see the final result. The heatshield needs to be put on before I can mount the bumper. The rear bumper is also different to the standard setup so there we have the next possible problem, but my measurements show that it should fit.

 

I wanted an exhaust that is not as loud as you can get for the sake of some HP to gain. Also watch closer: this is not the standard louvered core configuration. The louvered core is mounted backwards in this case.

Optimum for flow would be a perforated core. Optimum for sound would be a louvered core. This configuration is between these two worlds.

Perforated are louder, I tested both options as we experimenting.... I prefer the louvered... We also do not use steel wool for packing like most off the shelf mufflers...

 

looks like a great setup. love the tips! what would something like this cost if i may inquire?
