So i have all the mods in my sig. Im just got my FBD 5'' in the mail today, should be installing it on sunday. Just curious as to what you folks think will be gained as far as hp. I know companies like mbrp claim something like 30hp or so for their 4'' exhausts, only reason i went with a 5'' over a 4'' is i like the sound better, not because i expect more performance gains.

So what do you guys think?

you may be able to feel it a TINY bit down low but it really isnt that noticable

ya im really looking for the power down low for towing, i tow my jeep across the country several times per year. So im really hoping for maybe a tad better mileage, was only getting 12-13 pulling one jeep and trailer

nice. Im going from the stock exhaust to the 5'' and, to me anyway, it seems what when i added the injectors and cold air intake that and exhaust is the next step for performance. Im not trying to build a racer, just a pull truck

ya the only things left for this truck are a air dog or fass and then a box... other than that this truck is done. I like to keep my daily drivers low key... no need for huge power. And i like getting good mpg, thats why i chose a diesel over a big gas motor.

edit: i put the exhaust on yesterday... it is nice and loud... noticed a slight power increase, but i think i would feel more of a difference towing a load.

i get about 16mpg pulling my xj at 75mph.

it looks like from your avatar you have a camper shell. if it wasnt for the fact that i plan on getting a gooseneck i would buy one. I dont think i get 16 mpg empty at 75 lol

yes, it definitely helps! I'll get 20 unloaded.

20 combined? Cuz i can see 22 on the highway.
