i'm planning on one of these options.

1) removing the stock muffler and putting a Cherry bomb extreme muffler inplace of it.

2) putting a exhaust cut out infront of the muffler so when i tow my trailers i dont have to deal with a loud exhaust if i dont feel like it.

I have a cutout on my truck and a Magnaflow SIDO exhaust straight out back... sounds great inside and out. The cutout is flat out fun... would like to get an electric controller for it though.

yeah that cut out is something to think about

Just go to an exhaust shop. Single In/Dual Out muffler and two tail pipes, have a nice day. Choosing a muffler is of course a whole separate discussion.

05' Up SD gassers have weak aftermarket parts support when it comes to performance bolt-ons and the 08's are worse.

First off I wouldn't gut the cats. You have two of them on your truck and they really arn't too restrictive. They are expensive to replace if you have to.

Either build an exhaust yourself or go to an exhaust shop to get one custom bent. If you want duals a single in dual out muffler is best. (I'd go 3"in Dual 2.5" out) You can get a Flowmaster 2.5" Universal exhaust pipe kit for around $200 and that has a bunch of mandrel bends with it and is designed to slip together. Flowmasters pipes are good. The FM cat-back I have on my truck is a great system for the money.

An exhaust cut-out would be fun but you will lose low end power with it.

I just became the owner of a 2005 F250 SD with the 5.4l last week. The previous owner put duals on it from the cats, all the way back, with either Flowmasters or Dynaflows. I'm not sure which because I bought it from a Ford dealership, who had no clue. All I know is it sounds absolutely awesome!!!

thanks for all the help i was think about just gutting the cat and putting on a super 44 muffler with dual 45 out at the back behind the rear tires

I'm not sure you'd be able to gut the cats without a lot of work... I'm not a big Flowmaster fan but the Super 44 should sound good, loud and rumbley. Pretty much anything sounds good on these motors.

The super 44 doesn't have very much capacity to it, as it is has a 4" case. It will be loud and more than likely produce drone.

I'd go with a flowmaster muffler with a 5" case like the 50 SUV or the 50 HD FM mufflers.

Gutting the cats is a bad idea IMO especially on a new truck, you have 2 cats to contend with. If you do gut the cats stick a piece of straight pipe through them, otherwise you will get turbulance.

a flowmaster 50 might be your best bet:

I vote MagnaFlow just to be different and because of personal experience. Custom job at a muffler shop is best no matter what you go with. I like the nice firm sound of the MagnaFlow, very mature compared to some of the other mufflers out there. Quiet when you want it to be and plenty of sound when you put your foot into it.

Best fit in Magnaflow is the 24" long with 5" X 8" Oval with 3" single inlet and 3" dual outlet (Model # 12398). I prefer the 45 degree out behind the rear wheels. I had the dual straight out the back on my last truck and it was noisy with the trailer and a pain when hooking up as I kept getting exhaust blown in the face all the time.
