For anything metal related it is best to avoid any chemicals directly on the metal as it can fade the color, any chemical cleaners or lubricants generally do have mineral oil or some solvent based chemical in it that can affect the color of the metal, just one of those inherent qualities of metal surfaces.

However what is good about this system compared to others is those tips are REAL Titanium from their factory in Fuji Japan. Other cheaper brands often use Stainless Steel with a chemical coating which they apply to stainless steel and burn it. When those cheaper brand "Ti like tip systems" fade there is nothing you can do about it, they go a light color.

SO.... What you can do with this system since it is real Titanium is apply heat to it. If you take a blow torch to it, it will shift color being real Titanium however if you want to maintain the gradient you will have to be careful while doing it so its even, but even if you don't do it even you'll have a deep purple color which looks incredible, i highly suggest also cleaning it thoroughly with alcohol to ensure there are no other chemicals that can affect the color as you apply heat.

I've personally worked on some Porsche 911 Turbos and helped to produce Full Titanium Turbobacks in the past and those pie cut exhausts always shift color after driving it really hard from exhaust fumes being hot and it makes this really great bluish purple.

This isn't an exhaust and it is just spoons, but this random link I found quickily on youtube might shed some light on how to do it.

I hope this helps shed some light on your situation, and maybe a fun solution for you to try out! If you have any additional questions or need some more advice feel free to email me at Steven@modinjapan.com or pm us here!

I didn't realize I needed to take a torch to my exhaust every season. Now I know.

Doesn't change the fact that nothing is being done about the situation. But now everyone on this forum understands that the titanium tips need to be cleaned by rubbing alchohol
