OS 2090 for the XZB Speeds. OS 2060 for the VZB speeds.

Silly question whats the difference? I mean what power range is the 2090 better then 2060? I have the 2060 I'm planning on using with mine just wondering if its worth it to get the 2090.

The 2090 let's the xz based engines open up more on the top and makes them a little more responsive on the bottom to. Also somehow it adds a little mileage 20-30 sec. For that engine the 2090 is the pipe you want. The 2060/2090 header is the same and you can usually find the pipe without the header. Saves a few $$

The XZB engines are long stroke engines. The older VZB engines are short stroke engines. The 2090 is made for the XZB long stroke engines and the 2060 pipe is made for the short stroke VZB engines.

Yes, you can use the 2060 on the XZB and vice versa and the engine will run, but you won't get the maximum out of it.
