Does anyone know if the obx header for the xA is any good? I saw one on ebay for $150 shipped, so I'm pretty tempted. Also, I'm not planning on getting a full exhaust system since I like the quietness of the stock system. Would I still notice gains having only a new header?

Thanks!

If it's a 4-2-1, you'll see better gains in the lower to mid range of the powerband. A 4-1 header will provide better high end.
I have an MMW 4-2-1 and it's great. Along with the stock exhaust, you get power and keep it quiet. OBX is fine.

Here is a recent thread on the OBX 4-2-1.

I bought myself a set of OBX headers ($105 shipped for a brand new set!!). I'll post an update once I have them installed.
