Just to add my experience, not of power flow, but general custom exhaust. I've had two made from different places, one for a 3.5 elgrand and one for a 5g 2.2. the lude was my daily so I'd asked for slightly larger spec piping and a baffled rear box trying to emulate some specs I'd read ( the piping not the box). Anyway it ruined the car, it felt fine round town in sound wise, but was loud at motorway cruising speed and VTEC felt like it was suffocating. On the elgrand is had a full system based on factory sizing and boxes, it too was loud but I had no choice as there was no of the shelf option.
Best exhaust if has was a Remus rear box on an eg6 vti. It was absolutely normal at out of VTEC and beautiful in it.
Long story short... Choose carefully! And if I had to do it again... I just hope I don't but I reckon if it was a custom exhaust it would be in mild steel purely for the sound.
