equal length all the runners are the same length.they end up looking like a pretzel and are more of a pita to install.but they will net u a couple hp do to the balanced flow on all cylinders.unequal all the runners pretty much go straight to the collector.these are the more common of the 2.

Unequal length go from the nearest port on the heads and combine into one tube so rear tube is much shorter than front tube. . Equal length- each exhaust tube on the header is the same length whether it's the tube near the front or back of the engine which makes the header longer but equalizes any back pressure.

Re: header question.

If you are wanting a set of headers that allows you to use your current mid-pipe you will need to buy a set of shorties.

Equal length headers have every tube from the engine to the collector (where it connects to the mid-pipe) the same exact length. unequal length headers just run the pipe from the engine to the connector in the shortest route. The point of this is equal length headers allow the same flow and restriction for each cylinder equally.

I'd personally go with equal length headers , BBK makes chrome equal lengths for $229 but you can go higher with JBA and Bassani which are around $500-$600 new!

Will the equal length fit easy on my 5.0?
