Exhaust for 2011 F4

I am wanting to put pipes on my 2011 F4 but I'm looking for members advice. My main concerns are dropping some weight and obviously looks. The systems I am looking at are the RG4, Bodis and motocorse system.
I think the motocorse look the best but how do they perform and how much weight do you save? I've always loved that pipe organ look since I first seen an MV but the square pipes are growing on me. Does anyone recommend the RG4? I've heard they aren't much lighter than stock. The Bodis offer the round look and I've read good things about them on the forum but I am a bit concerned about how loud they might be. They do seem to give best bang for the buck from what I can tell.
Also is there much weight saving from any of these systems as a slip-on or is it all in the headers? I'm not necessarily craving the best HP numbers but for what I have to spend I would like a decent improvement.
If I did go the slip-on route do I need an ecu or some sort of fuel remapping device?

The Bodis will be the lightest as they are essentially just welded pipes with minimal noise restrictions.

The Bodis will be the LOUDEST thou.

the best looking one will be the Motocorse system but you do pay for it.

Slow is smooth and smooth is fast!!

Do you save much weight from the slip-on? Does the slip-on have removable baffles and if so how loud are they with the baffles in?

The Bodis for the 2011 model,have removeable baffles so you can have them as loud or quiet as you feel comfortable with by packing the baffles .They are very well made,look good and alot lighter than original/RG4 systems.But you need the race ECU.

Are you referring to both the slip-on and full systems being lighter and needing the race ecu or full system only?

You would need the ecu if going with the full system, weight savings=11.02 pounds

Does anybody have any experience with running the RG4 header and ecu with a Bodis exhaust? I am wondering if the ecu would need to be reprogrammed for the Bodis and if so how difficult is it? If I had to take it to a tuner to reprogram, would finding someone who can reprogram that ecu be difficult?

The bike will run rich after fitting the Bodis,thats why you need the race ECU,its adjustable,so your dealer can set the CO%.Easy with the right scan tool.
