Unsilenced B pipe sounds good, a bit louder than your average car on the road at normal speeds, a nice rasp and a good motorbike-y tone on full throttle, VTEC sounds nice. Unsilenced B pipe and an unsilenced backbox is better though, you could probably get an unsilenced backbox and a Spoon N1 rep from ebay for under £300, bought and fitted, if your budget is tight.

This video gives a good example of unsilenced B pipe and OEM backbox, that is exactly what mine sounded like when I had that setup on.
