Here's the one from my 525, and the spacers required for that bike.
Here's the ugly KTM branded pipe that came off my friend's 530, which he replaced with a new Q4, and the offset of the brackets is the same on his new one, requiring no spacers.
The purpley pipe is the KTM, and the one on the right came off my 525. The steekers fried off mine within 20 minutes of riding on the Bonneville Salt flats. The bikes ran quite lean there, but perfectly everywhere else in Utah.
