I think it's fairly clear that the full system works better than an end-can, however it also costs more money, and, as some people have said, you may not be keen on the idea of fitting it yourself, which adds expense.
If what you are after is sound and looks, then a full system isn't worth the money to you.
I think that it's agreed that M4 make lovely stuff, but they're not cheap, if you really are after sound then it may be best to look elsewhere anyway, you could spend a whole lot less money, and still have everything you want.
As far as remaps/Power Commanders go, if you fit a can you won't need to do any of that, it's true that there will be more to come if you do, but it's not essential and no damage will be done, bear in mind when it's said that it won't be fuelling properly with the can on, that there are gains to be had from an otherwise entirely standard bike if you remap it, but it would then produce more exhaust emissions than is legal, which is why the fuelling is the way it is out of the factory.

Thats a bit of a generalisation, on a personal note all I wanted was mainly a better looking can and a nicer sounding exhaust, okay so I was also after a bit more power, to me the extra I spent on getting a full system and rene air kit is money well spent. Not meaning to sound up myself, but I can afford it so why the not.

I also have a PC3 fitted, just need to get it properly setup (will be booking it in on friday), again some will say its a waste of money (especially if you see me ride) but from my point of view its what I wanted so I've got it.

If you can afford it and its what you want why the hell not just buy what makes you happy.

M4's full system is one of the best but power fiigures are arguable, earlier this year one of the racers on SVRider did a head to head with an M4, Akrapovic, Micron Two Brothers (IIRC) and Yoshi and found the Yoshi was best, but apart from the Two Brothers (or whatever the cheaper one was) and the Micron, there was less than half a horse peak in it. Can't find the topic now, durn it. The M4 was good for power but gave a very irregular curve. They didn't rejet for any of them, just ran them all with standard jetting which gives a reasonable comparison I think.

I really want to get a good comparison between them and my own WRP, anyone got a bunch of race systems and a dyno i can borrow?

I got my systems both for under £300, and I doubt I'd pay full whack for an SV system. For the power gains you get I don't think it would represent good value for money.

Being honest, most people want end cans because they look and sound good, and a slip-on will look almost as good and sound much the same. Full systems do have more cred with riders, though (especially very rare ones made entirely out of titanium ) and they look less bolted-on. Also, they're not at all hard to fit, so don't worry about that- I reckon it took me less time to fit the WRP than it did to cut the pipes and fit my CCC can.

Have a look at that header pipe. Tightest fitting pipe I've seen so far.

In my experience a full system won't give a massive improvement over a good slip on. What it will do is fill in the mid range and not really affect the top end.

Obviously this depends on the bike and the state of tune. Using a fuel injected SV650 as an example a few racers have upgraded from a slip on to a full system and not really gained much top end but have gained significantly in the middle.

Power Commanders and the like will give you a greater benefit but a simple remapping job with a plug in Teka or Yoshi box give better value for money.

my experience too, but for street riding, the middle is more important is also my experience

Doesn't the Yoshi box change the mapping permanently though, unlike a PowerCommander? I had my bike (GSXR600) dyno'd and the PC re-mapping raised the power at the back wheel from 92.5hp to 102 - it was running lean but that's a good 4hp above standard and that's with a end can and K&N filter. If you are going for a full sysytem I would get a PC to ensure I got maximum benefit - and the dyno time cost £150 so greater expense. If you have loads of money to spend get the full sysytem, decent filter, PC and dyno time - otherwise get a slip on, save wads and enjoy the sound!

Hey Mitch, I have a full M4 system that I'm going to flog as soon as I can get the rear header off, I'm down in DE. I believe it's the aluminium version, oval. The only problem is that the fat effer before me had lowered the rear so it has ding off the swingarm, but you cannot see it when it is on the bike. MAke me an offer? I can send you some piccies if you want to let me have your e-mail.....and give me time to take the header off, I'm not always the most pro active but will be giving it a go this weekend.
