Well I'm well pleased with the end product. Exhaust note is very subtle with only a hint of "RB" until I give it a bit and it howls away nicely, not too loud, just the way i was hoping. A little stuffing around according to Daryl from Everlast to make the cat back fit but nothing major. Highly recommend them if you're around the area, they've now done quite a few Stag's.
And if anyones wants a stock standard Series 2 cat+catback exhaust, $50 and it's yours.
