So right now I have MAC LT's which are 15/8 primaries to 2 1/2 collector on my 2004 cobra with a kenne bell 2.2 blower. If I go to 1 7/8 primaries to 3in offroad x, to 3in exhaust would I see any valuable gains if so aproximately how much should I expect to gain? Just curious if worth the extra coin because 2 1/12in. Exhaust and small headers seem to be choking off engine in my opinion but I could be wrong. Any input is appreciated thanks.
Would I benefit from doing this mod?

How much power are you making? Your current exhaust is likely plenty big enough. You probably wouldn't see 15 HP difference in changing it out.
608rwhp
15-20rwhp would be my guess. You aren't bottle necking much.
