New Modular Exhaust System for My Car

New Modular Exhaust System for My Car
Having read numerous postings re exhaust systems for Porsche GT cars and having reviewed the aftermarket systems currently available, I have concluded that nothing commercially available has the flexibility of componentry and/or the quality of manufacture that I desire. Given this, I have designed my own exhaust system with every major component being made to as high a standard as possible and each being infinitely and rapidly interchangeable though the use of quick release clamps. As a result, depending upon conditions and varying desire for weight reduction, altering horsepower and toque and/or
sound as well as legal considerations, such components are as shown above with Grey = Titanium, Green = Inconel and the one set of Green Clamps = Stainless Steel.
P.S. The system should be built by April.

Looks great although there are many people doing this now to the same standards I have a Ti by pass already which hits the scales at a very small 3.6 lbs.

Curiously you're not going for a center merge in your final section?

Re mrd_spy: (1) while others are making exhaust components from titanium, the quality of materials and manufacture can and does vary greatly; and (2) given the oxidation temperature of Ti, I would maintain that it is not the must suitable material at high temperatures, e.g., for the headers, catalytic converters.
Re CRex: could you provide a picture of a "center merge"?
Re MMuller: Regardless of claims, in particular for a normally aspirated engine, if completely objective and clinical tests are made, in precisely like conditions, I doubt if any one exhaust system truly produces more than a few more or less HP than does another system, i.e., the actual performance gain or loss is, if at all (other than, perhaps, in the mind) noticeable to an amateur driver such as myself.
Re 80p: sound is totally subjective, many people buy an exhaust system based upon the sound, I do not. The key factors for me are: (1) overall build quality, (2) weight and (3) any noticeable performance change.

Interesting analysis. I ended up with this Akrapovic set up for all the reasons you detailed.

Ironically I spoke with another major aftermarket exhaust supplier this afternoon who was honest enough to admit that the like for like performance differences between exhaust systems is minimal at best, i.e., a few HP.

As Robert has correctly stated, most drivers would not be able to perceive a small hp bump, it’s also true that many drivers would also not feel a weight reduction in the rear on a 3000 lbs plus car.
