Titanium Exhaust
I’ve read about Agency Power’s titanium exhaust system for the 997 and what really caught my eye was the claim that it eliminates 46 lbs from the rear of the car. These are not inexpensive systems. However, reducing rear engine weight must be of great benefit. So, I’m writing to ask if anyone has any experience with these exhaust systems? What are the benefits and are there any drawbacks? And, given I have a bad back, I’m wondering if the reduced weight has a bad effect on ride comfort? Also, is it true that titanium exhausts are prone to cracking?
Any and all info appreciated!
Thanks,
John

Yes titanium does crack over time. It is not as flexible as stainless but it would take quite a while before you should worry about that. Ti exhausts are really light but many of the newer stainless systems are relatively light as well.

The weight reduction would be less than half a tank of gas. I doubt you would notice it. If you got rid of 46 lbs of unsprung weight, you might notice a better ride on bumpy surfaces. Slightly.

Anytime you can eliminate weight, it's a good thing as long as it's not at the expense of something else like sound, reliability, longevity, etc. Unsprung weight makes a big difference but the exhaust isn't that.

46 lbs removed from the rear of a 997 has got to make a significant difference in terms of increasing the power to weight ratio and reducing the pendulum effect when cornering. Ride comfort is a question of how the suspension would react ... I would think that adding weight would soften rear suspension, although it would reduce suspension travel and so maybe reducing weight would improve the ride - depends also on how this suspension is configured? Adding horsepower is another question?
What I’d like to do, ideally, is have my SS headers and such an exhaust system ceramic coated to contain and move heat out the tail pipes, which would reduce the engines operating temperature, increase horsepower and improve longevity!
I was hoping someone with experience could chime in! But, given the price of admission, I’m guessing such a person is a rare bird!

The 2002 Corvette Z06 had a full titanium cat back and mufflers. Back in the day, I swapped one on my C5 convertible. Amazingly light. Like 30lbs lighter as I recall.
I would be amazed if it saved 46lbs on the 997. That would be a significant difference.

That is a huge amount of weight savings giving the length of our exhaust system. Is this a straight pipe? 46 lbs off the back of this car would improve tracktime if you're already using your car at 10/10. As others have mentioned, I would look into lightweight wheels/brake components before a titanium exhaust but that would be a huge amount of weight savings if true. For reference, sharkwerks center muffler delete saves something small like 8 lbs.

The real truth about Ti exhausts is that they are just so friggin sexy to look at.
