How much more power will this give me???

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

i noticed quite a bit of improvement when i replaced the downpipe. seemed to pull harder on the top end.

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

for pulling your jeep, just get a box after the exhaust and you'll be done. i pull my cherokee up any hill i want at 75mph. the only time i have to slow odwn is if it's hot out; the temp starts to creep up.

you currently runnin stock exhaust(muffler and all)? yeah you'll prolly notice a difference...and it'll sound a LOT better than it does now

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.

here is a post I started (not long ago) and it took off! I'm very surprised it has done so well. any way it has guys who have dyno'd their trucks and has them post mods so you can compare yours to theirs, you might get lucky and find one that posts hp gains thats silimar to yours
Hope this helps

the bigger exhuast will lower egts too while your towing which will be a good thing. when i went from my stock pipe with muffler, resanator deletes, to a 4" str8 pipe, WOW! it was a very noticeable difference.

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

Well 5" is usually reserved for the very high end, high rpm generating machines. You will see some EGT reductions which will allow you to stay in the throttle longer, but I would have gone with a 4" Exhaust doesn't make power it just enables you to move the exhaust out of the way to reduce EGT's which allows you to apply more fuel. That is where the power comes from..... Always great to ask the questions after you make the purchase...
