5" vs 4" exhaust ( which is better??)

Which is better for power, 4" or 5" exhaust??

I know 5" is louder but does it deliver more power?

Well I'll just answer ur questions then wasting time telling you to search. There isn't gonna be a difference power wise between the two...it's mostly gonna be sound...a 4 inch will handle more then enough power
