Question 4-2-1 exhaust question

Can a raceland 4-2-1 manifold be in conjunction with a standard 16v exhaust system? If so would there be any advatages or would it be better to go for a pug sport aswell?
Also for the 16v engine is a 4-2-1 manifold better than a 4-1 manifold it seems everyone on here is going for the 4-2-1 route.

Thanx for any help

first question is that yes you would notice a slight difference as the exhaust gases would flow more freely, but would get jammed up by the cat, so would see an enourmous improve when coupled with a pugsport. But you can still use the standard exhaust.

second question is simple, 4-2-1 = better acceleration and 4-1 = better top end.
