M4 on 2006 VFR800

So, some time ago I took on a task I have only been dreaming of for my beloved VFR.  Short history, I had a SV650S before the VFR and had a M4 Carbon Fiber can on the bike.  I loved the sound, it was deep and throaty but without being too loud. I kind of wanted the same thing for the VFR but I didn't really want to go with Leo Vince (even though their prices have dropped) and wanted the Stain Tune but without the price (and they didn't have Carbon Fiber).  So I got to thinking about if I could fab up a way to put the M4's on the VFR.  I ran the measurements, taking into account the stock luggage rack, which I use daily.  A buddy of mine can weld, big bonus.  I called up M4, they made a custom can, wrapped reverse, to match the can I already had for the SV so I had a matching set.  And thus the fabrication began.  At first I was all set to cut the cans down but in the end, with the stock luggage on the bike, it doesn't look to bad.

FYI, the exhaust system, minus the cans weighs in at 9lbs. lighter.  The M4's weighed only 4lbs. so I netted a loss of 5lbs. on the total exhaust.

Here is the size difference in the M4 and the stock exhaust that had to be made up

Totally welded.

There is about 1/16"-1/8" clearance at the proper angle with the stock luggage rack.  No rubbing, no touching all the way around.  The cans stick out about 3" further than stock, but as I rarely take the side cases off, the lines flow rather nicely between the top case rack to the cans to the side cases.

Now the changes to the stock exhaust are permanent but the cans are now truely slip on.  This means I don't need to dissassemble the entire rear end of the bike to take off the exhaust.  This is so nice.  There are probably smaller carbon cans on the market but the M4's were cheapest for the SV so I stuck with that, plus I already had one can and only needed to order the other, not too bad.

Nice job! Carbon fibre is the way to go....

Wow, that sounds and looks amazing! Great work.  Love the carbon fiber.

Nice of them to be accomodating and build you a can that is the reverse of the one you already had.

Good work.

Looks nice other than the cans are too long! :ph34r:

I would cut at least 3-4" off of them to make them at least no longer than stock cans. I did the same with some other carbon cans and shortened them to 9". I like Shorties!   :tongue:

LOL.  When I first saw this post I thought "the guy is asking for advice on how to carry his assault rifle around on the bike?"

I thought he had mounted an assault rifle!  That woulda been badazz, but also kinda pscho all at the same time!

Looks great Ranger! That 's good while the exhaust and the OEM saddle racks have enough clearance.
Any more finished photos

I plan on moving the bikes in the garage tomorrow to get ready for riding season.  I will get a few more photos.

As for the assault rifle, can't say the thought didn't cross my mind.

How much for the mufflers, Ranger?

Any chance you can re-post the exhaust video clip? I can get it to work anymore. I would be willing to upload to Youtube if you can email me the file.

Nice looking and sounding set, and I agree that with the hard bags mounted the new cans look good.  Otherwise just too long for my taste.  But it's not my bike, so it's in the eye of the beholder.   :wink:

I'm in favor of taking a few inches off of the overall length of the carbons, at LEAST down to stock position.  I couldn't even stand that and took another 4" off of the stock length for a real "short OEM" look.  I'm keeping my eyes peeled for that video!
