Best 5" exhaust questions?

[REDL1NE]

I'm ready to pull the trigger on a downpipe back dpf/doc delete 5" exhaust. I've pm'd a couple of vendors on here expressing my interest in buying a new exhaust but I received no responses. I have a couple of questions:
1. Do I need to get a set that comes with bungs, or without bungs?
2. Flo-Pro make a 4" replacement downpipe. FLO~PRO 4" Downpipe 08-10 6.4L Ford Po werstroke 841
A. Isn't the stock downpipe 4"?
B. Is there any gains to be had by going with this downpipe.
3. Is there a 5" dual exit exhaust? The real question is should I have a dual exit exhaust.
4. I plan on using 7" tip(s) that are black or powdercoated...not a question
5. which is the best brand for this application?
6. Who should I order from?

The bung question all depends on which tuner you choose H&S do not require any bungs , all other i think do use bungs in the pipe . The stock down pipe looks like it's 4" but it's not , it is a double walled pipe , probably for sound deadening and heat . I have the FLO PRO 4" S/S downpipe but i put it on when i put my 5" FLO PRO straight pipe exhaust on , so i don't know what the inprovements are alone . Most guys i asked said spool-up was better along with egt's being cooler . A 5" dual exhaust i really don't know if anyone offer it, 5" pipes a pretty big to have duals . I am pretty happy with the 5" S/S FLO-PRO system i have , the down pipe requires two people to put it in , one from the top and second set of hands underneath the truck .

1) it depends on which tuner you get.
2)yes the stock downpipe is 4". i dont really know if theres much of a gain from getting this except some lower EGTs.
3) there's only a 4" dual exit exhaust. (or atleast i've never found a 5")
4) awesome!!!!!
5) i would recommend flo pro. it fits great and is a good product.
6) i've never ordered from rudy's, but i've heard countless good things about them. so i'm sure they would be a good choice. i ordered mine from performance truck products, and he gave me a great deal.

hope this helps man!
