Aftermarket header, is it worth it?

[jedman]

I have a 416ex with a HRC cam, stage 2 jets, and a slip-on White Brothers e-series exhaust. I was thinking about getting an aftermarket header, but is the horsepower noticeable? I'd be willing to get a new full exhaust if it will make a very noticeable difference. I see that everybody loves the Sparks X-6, but how loud is it compared to what I have? Any recommendations would be greatly appreciated.

Get a full system, slip ons don't do that much or any thing at all. I heard the sparks is good and it is louder. You should try to get something that adds a decent amount of power but isn't the loudest thing around.

If your up in compression with a high rev cam it would be to your advantage to go with one. Sparks DOES work and it is somewhat loud.;)
