Do MPE Ti tips change color?

[Lojs]

Can any of those who had MPE with titanium tips for a while now say anything about the change in appearance? Do you notice any bluish shade inside/outside of the tips over time?

So far the tips have not changed colour, however some areas of the canister have turned blueish/orange.

Titanium begins to turn color at 600 degrees Fahrenheit. Unless you take a torch to your exhaust tips, I doubt they will change color.

The canister is made out of stainless steel and the brown discoloration is, I believe, due to iron oxidation when it is heated.

No it will not change color. Ive had my MPE for about 3-4 months. I also DD it.

The entire rear-section of the MPE is made of Titanium. Only the mid-section H-pipe is made of "light-weight" stainless steel.

Thanks, I assumed the rear silencer ended where the pipes met the canister but I guess not.
