I'm not too sure whether I'm too late to add my two cents, but I think the exhaust pipes should be as straight as possible from the downpipe to the tip, with minimal bends.

As little back pressure as possible would be ideal for better spooling of the turbos.

Exhuast note: low rpms should be bassy and high rpms should be a roar

Lightweight assembly at a 'reasonable' price.
