On a system that has a muffler, one will not see much benefit of equal length tubes though it is still a little bit. Collector diameter and length has a major effect on power.
I made up a set of headers for my 88 Beretta GT. Made one side 28” and the other side 32” with a 3” collector feeding a modified cat and onwards to the muffler and out. Really woke up the 2.8 as it dropped the back pressure by 4# at 5500 rpm.
I was fortunate to have a second engine on a stand to mock up the engine compartment. Using u-bends and lots of cutting and fitting. I did purchase tube connectors to help in the welding. Once done, I had them coated inside and out with Jet Hot, otherwise the tubing would of rusted out in a few very short years.
