Quick exhaust question ???

Quick exhaust question ???
Alright got my 4" exhaust today they gave me enough pipe to just bypass the Muffler completly. Louder is not what I am looking for I got it for the power gains and hopefully mileage improvements. the muffler is a straight flow thru design.
My question is will leaving the muffler off be a improvment on the exhaust in power and that? Or is it just going ot make it louder?
BTW, 2000 PSD on a F450 tow truck.

i dought it will make any noticeable improvment in power/mileage. it will make it louder. i have the same type of muffler and did not think it was that loud...until one day my wife was driving the truck and when she pulled out of the driveway, i thought "man that thing is pretty loud", plus she is a little bit of a lead foot

i think it is supposed to help the turbo wind up faster and lower the egt temps for the engine, as for the power gains i am not sure how much, i am interested to find out how much more power it will have. and i guess of course it will be louder with no muffler on it. hope this helps, i hope i am right with the info i gave you, but if i am not someone will correct me.

I've got a friend that installs propane injection and conversions for a living and he did some dyno testing on different exhaust set-ups. The results show no noticeable difference between the aftermarket straight-through mufflers and running a straight-pipe. I left my in, did gut the catalytic converter though and had some gains there.

as for helping the turbo wind up i also chopped out the cat on every one also and the thing will rev as fast as a gasser now. milage increased slightly when the cat was removed, you said you dont have a cat so you will not notice this, but to everyone else reading this, straight exhaust will give you an improvement on fuel by maybe 2 MPG if you are nice to it. i can now abtain 18MPG in a 7k truck with 4.10's and an auto. could only get about 14 when i bought it stock.
