Think of it this way... I once took a driver's license test and got the following question wrong....
What is the first thing you do to brake when going down a hill or coming to a stop?
The test gave 4 answers to choose from. I chose something about applying the brakes.
The correct answer is that you remove your foot from the acellerator peddal. The engine is the initial brake. It is the power to move the vehicle forward.
When in neutral you are denying yourself the use of an important tool. And, with a manual tranny you may not get it back into gear when you are flying down a hill out of control.
I also believe it is illegal.

It is illegal in most (if not all) states, yes, that said I did have to test-drive a Mercury Grand Marquis last week that the customer did not leave me keys for its locking gas cap, it was running very low on fuel but it absolutely had to be tried out (been chasing gremlins for a week at that point, customer getting impatient, parts take forever to get delivered, you get the idea) so to save on fuel I shifted her into neutral when I got on top of the mountain and idled her all the way down - it is scary how quick this 4000 lbs landyacht picks up speed, and how much more I had to apply the brakes (both push harder and hold longer) to keep my speed within reasonable limits. Having a tractor-trailer as my first-ever vehicle to drive, I'm absolutely totally 110% sold on engine braking, to the point where I have modified my F350's automatic transmission to provide engine braking on downhills so on 8% or less grades I don't even have to touch my brakes to maintain speed.
or is it exahust brake i have been thinking of getting one in my truck
does the engine make a different noise
If I remember right, Exhaust brakes are not recommended for the IDI. We have hydraulic lifters and you run the risk of "floating" a valve and having it contact the piston. That would be a bad thing. I think he is talking about the Torque Convertor Lock up mod.

Chuck is right, I have my converter on a switch, it can get a bit annoying after a while and other than me only my best buddy and an ex-girlfriend can drive this thing right, but considering the results I can live with that no problem You having a hand-shaker, just downshift and let off the throttle, no mods needed for your trans, except maybe a SMF when time comes.
About the exhaust brakes, there are ones out there designed to work with our engines, they do run lower backpressures than say Cummins or D-max stuff due to reasons Chuck mentioned, but they work nevertheless. I'd love to have one in my truck, but the cost is highly prohibitive for me...
A friend of mine put one on his manual trans Dodge and he says it's real effective. I haven't ridden in it since it was installed. I was always skeptical of them because I've driven a few mid-duty trucks with exhaust brakes (Blue Ox--they don't make Jake Brakes for mid-duty diesels) and you couldn't feel hardly any braking at all, but evidently they work well in pickups, Dodges anyway.
I have an exhaust brake on a banks turboed 6.9l. I have tried it, and have not noticed the valves floating at all. not saying it couldn't just hasn't. I don't have a need for it, it was on my van when I bought it. Here is a pic of the van it is on. The guy was a nut that I bought it from, did everything he could to it to pimp it out. Banks, Gear vendor, Exhaust brake, gauges, 4x4, bed in the rear, the whole 9 yards.

Looks like he also attached a sacrificial chevy to the front!

Valve floating is where they are held open do to excess RPM's, or pressure, and not closing all the way as they should on a normal cycle. Hold an old gasser to the floor with no rev limiter, and you will hear it for sure.
