So, the bluish/purplish coloring on my Q300 was already kinda tarnished in a couple of spots when I bought the exhaust (used), and then when I tried to polish it up the color came off a bit more. Does anyone know how, or have the capabilities to replenish the "burnt" look to my exhaust tips?
I thought about getting a cheapo torch from Walmart and just trying to discolor it with fire, but surely it can't be that easy, lol.

Is the q300 stainless steel or titanium?

EDIT: I just looked it up...the tips are titanium.

That's actually better, I can (theoretically) do titanium easier than stainless. Let me get through Perryville and we'll figure something out.

Keep me posted on this. I got the same problem.

No they're not. The tips are stainless.
They just do the burn from the factory to give you a titanium look. They're 100% stainless.

Straight from Invidia's website:

It'll be pretty easy to tell. Torch will make both blue, but you can do titanium with an electrolytic solution at room temperature (sort of like anodizing aluminum). Well, you can do stainless that way too, but it takes some chemicals that are not exactly OSHA recommended.

I just emailed the contact on invidia's website. If they're lying, I'll have the lie in writing, lol.

That's how Invidia advertises them. RSD goes off the description their vendor gives.
Call Invidia and ask them what the actual material of the tips is.
There's very few exhausts that have any titanium in them. Tomei and I think the gReddy Ti-C

Tomei and I think the gReddy Ti-C That's not advertising, that's straight up calling it titanium, making it out of something else instead, and then selling it as titanium. That's not right. If this is the case, I'll never buy another Invidia product as long as I live.

I'm trying to find the thread I was reading that actually tested them...and basically they are both SS, one is burned and one is polished.

That should be an easy way to tell. Titanium is not magnetic. 200 and 400 grade stainless are magnetic; 300 grade is not. Well, that's a simplification, 300-grade can be if you cold work it enough. But generally, good stainless is non-magnetic. Easiest way to tell will be to try anodizing it before we get out a torch. I'm pretty sure stainless won't anodize without some chemicals that I won't handle without a faceshield and elbow-length gloves. Titanium will anodize with a 9V and coke. Speaking of, I need to see if aluminum will do that... Lol, if you felt like dropping the tips, i have a machine at work that would tell us in about 60 seconds. Or if we weighed it and measured the water displaced (titanium is ~half the density of steel). And, xti, it kind of is as easy as discoloring it with fire. If you want to try it yourself, make sure you have a water source handy to quench it - if it's too hot, or hot for too long, it will eventually turn a boring gray color. The good news, as you have found, is that it sands right off. The other thing is that you should do it as quickly as possible - if it's cheap-good stainless (which is probably is), staying that hot for very long will precipitate an embrittling phase that decreases the corrosion resistance - the pipe will literally start to disintegrate in corrosive environments (what would probably happen is that it would crack after a few winters). You should have a good 15-30 minutes at the temperatures that stainless turns pretty colors though. Fun fact, that's why the Killer B headers are a stainless alloy no one has ever heard of - and they're the only ones I will ever use if I go aftermarket headers.

300 grade stainless will become magnetic over time due to heat exposure to. At work all of our dies are varying grades of 300 grade and at 700° and up after a while they have regained the magnetic properties.

700 C or F? Interesting that it picks up magnetism if it's F.
