I am currently having a unique stainless custom header made for my RX8 and I have the ability to also get a titanium exhaust from that point back. I am not sure if it's a good idea or not. Does titanium last long? Is it durable? Can it withstand a lot of heat from a rotary? Does it allow more heat to escape and heat components like the transmission and diff more?

If anyone has any knowledge on this please share.

Thanks,
Stephen
