Got an email from Cargraphic, the exhaust tip will arrive Monday from Germany. I had one on my coupe, and it is to me the nicest tip available-a little bigger than stock, and thicker and polished. Really dresses up the rear of the car, and it's bolt on so no welding.

Damian-

Stock cat/resonator/muffler?

Yes, Bob, everything else is stock. They also offer a high flow cat and their own exhaust system, but it's very pricey-and they've been unable to give me dyno sheets backing up the claimed hp gain with their parts. This is a cosmetic upgrade only-I think it looks better than either early or late stock tip, or the B&B tip, which is round-this follows the shape of the cutout nicely. When 968.net comes back up there are some shots of my old coupe with the Cargraphic tip in the archives somewhere.

Damian-

I'm starting to doubt if we will see the forum soon- I wish I had stored data on the many small projects so well documented. All the bitching about the 'search' issues seems so petty today...

I am about to start the steering wheel replacement and have the DIY form Tom's site- but the info on the eggcrate replacement is in Forum Hell...

Bob, let me know how your steering wheel install goes. Raj and I are using the 'Rimas' method of using a late 944 turn signal switch and cruise control assembly to avoid having to cut and splice.

Bob, I know the eggcrate procedure inside out. Let me know if you need help.

I think there's horsepower to be gained with a high flow 968 exhaust system.

What people forget is that there's tuning involved, also. The reason people can't just bolt up an exhaust and see any horsepower gains with the 968 is because the stock exhaust is very well tuned to the factory fuel delivery maps.

If you buy an exhaust system with less restriction then you'll sacrifice some low-end breathing [torque] meaning you have to take out fuel to compensate. Then you'll make more horsepower on the top end IF YOU ADD MORE FUEL!! The only person I've seen understand this is Mark in New Zealand...if you're going to flow more air, you need more fuel to make power.

The concept is that simple. Guys have just installed exhaust systems and complained that it does nothing for performance, because they're running the engine lean. If they tune it [like Mark did] they'll probably see 10 or 15+ horsepower.

Remember, Porsche built this car with the 75 lb-ft of torque benchmark in mind. If it was torque they were after then there should be room to make significant power in the exhaust...the restrictive muffler/resonator combo also supports this.

I wonder what would happen if a high flow system was installed and an adjustable FPR installed with 1 or 2 psi of extra fuel to the engine. Hmm... <img border="0" title="" alt="[Wink]" src="wink.gif" />
