Yes, you can buy X50 tips but be prepared to take out a bank loan to pay. I have used the Techart ones myself and they too are expensive.

Dansk has knockoff X50 tips and they aren't too expensive.

I bought these of ebay $150 and after a year they are still very good....

any chance you could post a pic of them on your car? In the pictures it looks like there is a little bit of excess bulk of metal where the twin tips 'merge' together. When that's all you're looking at in the picture you notice it, but I can't imagine that it's something too noticeable on the car. Especially given the price difference!!

 

+1, id like to see them as well. Hate to pay 500 for something that should be 150 bux.
