Downfiring vs Forward

[BoondockSaints]

So Im trying to decide between two different boxs for under the seat of my dodge ram, not much choice space wise but I found a few boxes on the internet and was wondering 2 things. 1) Should I go with downfiring or forward firing 2) Do any of these just look wrong lol?

Ebay Box (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&itemcount=4&sspagename=MERC_VI_RSCC_Pr4_PcY_BIN_Stores_IT&usedrule2=CrossSell_LogicX&refwidgetloc=active_view_item&usedrule1=StoreCatToStoreCat&viewitem=&refitem=300108115661&item=300106779766&refwidgettype=cross_promot_widget)

go with the ebay one the downfiring dosent even matter but the ebay will be better suited since it has 1.2 cuft per chamber vs.. the downfireing one that only has .55
