There is room for more TQ in low end and a few hp, the system I have does that. It goes from manifold to end, so its proven.
Muffler only, not sure. Stock mufflers are quite restrictive, BMP and Magnaflow are probably less restricitve.
EDIT
if you google "128i race car" you will see what the single exhaust would look like
