Questions about DownPipes

Hello all... I just have a few questions about downpipes and am looking to get some information. 1st off are downpipes worth it? what would I be looking at as far as HP gains? Currently I have a borla catback and am running JB4 on map 1 i heard I would be good to go on map 2 with full exhaust is that true? I dont wanna over work the turbos so i have always kept it at map 1. Also which DP do you guys recommend (i am an Xi so idk if that matters) Lastly how much am i looking at as far as install for the DPs, overall im just trying to figure out if it is worth the price to upgrade from the stock DPs thanks for your help
