Good info Blinx, you should have a go on the local NZHondas.com forum, there's a couple of guys on there who love to argue about the "back pressure" myth.
Here's a bit of a story to throw into the mix:
Got 98 spec ITR headers on the B16b (with 2.5 inch collector added), with stock block and head, and of course the ITBs. Tuned with Hondata.
Had a 2.5 inch exhaust with a 900mm resonator in the middle, under the tank and out the side JDM N1 style.
Just changed the exhaust to a twin side exit (out both sides) and boy what a difference! It sounds a bit like a rotary engine (brap brap brap) on idle but at full noise its wondrous, and the power up high is much smoother and stronger.
Care to theorise as to why?
