4" downpipe worth it

When I got this truck it had a mbrp 5" muffler delete kit but it still has the factory downpipe. Was wandering if you guys thought it would be worth the price to get a true 4" downpipe. Or would I not see anything to justify the cost. Thanks

my truck was the same way when i bought it. had 4 inch straight pipe and stock downpipe.
i recently put full 4 inch exhaust and i noticed about a 50-100 degree drop in temps and about 2 more pounds of boost. also a little more top end power.
thats just my experience.
