Generally speaking, Titanium is actually a less than ideal material to build exhausts from. It's structural strength is greatly reduced at anything above 400-500 degrees C, and commercially pure titanium can begin to oxidise at the kind of temperatures car exhausts reach.
The alloy we use is specially sourced by ourselves and very VERY rare in the UK. It's specifically designed to withstand heat 300-400 degrees C higher than commercially pure Titanium for extended periods of time, and at least 200 degrees C higher most other high-temp Ti alloys making it the optimised material to use.
It's an extremely difficult material to work with and even more difficult to weld, meaning it requires a very specific set of skills in order to ensure the system is manufactured correctly.
All welds are fully gas covered (hence the silver/straw weld colour) and back-purged to within a micron of their life in order to ensure complete structural integrity.
