header
 

hey all im about ready to add a header to my fi 78 280z looking at the msa catalog between the three into two and the equal length headers they offer what would be the best do you think for good street power any one have experience with either or is there a better choice somewhere else?

The equal length six into one headers are supposed to be the best overall for the smooth torque curve and better hosepower on the high end. Probably talking about +5 lbs and maybe +8 hp over the simple six into two headers. This would be on a modified engine of course. Stock engines may see even less difference if any.

If the cost is worth it to you, go for the equal length. If you're running a 2.25 inch exhaust or smaller for better mid range power, then either header should work the same.
