Aluminised steel is cheap and often adequate while titanium is expensive and long-lived. This compares the two on service life, heat, weight and the total cost of ownership.
Exhaust heat reaches nearby parts by radiation and conduction. This looks at what suffers first, what titanium does and does not change, and how blankets and shields are chosen.
Titanium saves mass mainly through thinner walls and lighter flanges, hangers and brackets. This breaks down where the saving really comes from and where the argument is weakest.
Cracks in titanium exhaust parts usually start at joints and hangers. This covers what can be welded again, what cannot reasonably be saved, and how a splice should be prepared.
A cold exhaust does not sound like a hot one. This explains how thermal expansion, damping and condensation change the note, and why titanium shifts further than stainless steel.
A valved exhaust uses an actuator to move a butterfly in the pipe, switching between a quiet and a loud path. Here is how each part works and what the common faults usually mean.
Titanium tips colour because of a thin oxide film that grows with heat rather than any coating. This explains how blue and purple finishes form, how they age and how to keep them.
Wall thickness, packing density and internal layout decide how a titanium muffler sounds and how long it keeps that sound. A practical explanation for enthusiasts, workshops and buyers.
