Titanium vs Stainless Steel

[BunkerBeezy]

I think Pagani uses carbotanium

On topic though a titanium exhaust sounds awesome

pagani uses carbotanium for its hull/shell in which the driver is in. there exhaust is full ti its made buy a company the makes all the exhaust for the LeMans Prototype cars. the exhaust alone is worth 50 stacks + ..... and OP after you finish your grease monkey ti exhaust with your dad who sounds like the best mechanic ever cause he puts small blocks and big blocks together in old buckets send me some pictures love to see the welds and if it can with stand being dropped and not crack at the seams .. GL :thumbup:

Titanium is not ideal for high heat continuous applications - like next to a turbo. Formula 1 moved away from Ti and went to inconel for most of their exhausts. A normally aspirated motor (like a motorcycle) with good air flow around the exhaust (like a motorcycle) can keep Ti from overheating. Ti becomes brittle with constant exposure to high heat. Bent tubing is preferable to pie cuts, especially in high heat areas. Having a canister or muffler in ti makes sense - good weight savings. Stainless is much better than ti and far cheaper than inconel for anything close to the manifold or turbo itself. lots more reliability and strength. Welding Ti is very tough, and usually requires an argon filled chamber for best results. some of the pics above show robot welds (where you see banding to each side of the weld). Hand welding ti and making it work well (strong) without a chamber is really tough, probably fine for a muffler or end pipe, but for a header or turbo flange, good luck... makes welding thin sheet aluminum look easy by comparison.
