Lets clear the air. Some people like the design of the Quat-D Full System and others not so much. For those our there on the fence about purchasing the system this post is for you. For those with what I would consider the equally as nice Termi system, sleep well your nice carbon can is still 3' feet off the ground.
So about a week ago I purchased a full Quat-D System from a fellow Ducati.mser (What do we call ourselves on this board?) and received it in the mail shortly afterwards well packed, Thanks!
I figured retail therapy was a great way to cure my
stalling blues.
So lets begin!
The Quat-D system itself:
After opening the box all I could say was WOW!

It was beautiful and crazy light! Infact I quantify how light, see further down the post.
All the welds were gorgeous and the QD logo was laser etched on the header like the new high-end Ohlins stuff.
Let the installation begin:
First of all I found out all the instructions were in Italian, not good.
So I went the
Quat-D website and the front door was in english, but then the details page was still in Italian, was on my own for this installation except for about 3 pictures on the instructions.
Well first step had to be taking off the old system. I ranted about this in the
Mmmm Quality ....not! thread, so all I’ll say here is that Ducati ought to raise their prices about $50 and include some nicer fasteners that are more impervious to the weather.
After getting off the stock exhaust I decided it would be an optimal time to actually see what it weighs:
Well after weighing all the associated peices it looks like about
: 23.36 lbs (10.59kgs for you metric folk). Hell the can alone weighed about 11.34lbs.
How about the Quat-D system: 9.92lbs (4.49kgs)
So the the estimated weight savings of 7kg (6.1kg actual) is pretty accurate.
Assembly, from what I could gather I was supposed to put the front and rear headers on and then mount the mid pipe:
I found the easiest way after about an hour was to first not cinch down both the front and rear all the way in fact leave the quite loose and then then slide the mid-pipe over the front header and then mate it up to the rear header. Make sure you put the cinch clamp on before you try to mate the front header

. The fit will put the header very close to the swingarm. I tried multiple times to get a bit more room but thats the way it appears to fit. It looks like the cornering clearance has been improved by moving the front header inboard, this looks to come at the cost of overall ground clearance though, for my riding style (less jumps, more lean angle) this is a good trade off.
Gotcha note: Make sure to remove the bottom stack Cat mount bracket which opens the hole in the back of the engine case. To do this you will need to remove the rear most rearset bolt and loosen the front one. Then you should be ready to get the mid-pipe in the correct position. This took me a while to figure out I hope I save somebody out there a bit of time.
Once the mid-pipe was in place and all the mounting bolts lined up I tightened up the header bolts and the can just slips over the mid-pipe with a couple retaining springs. The exhaust strap to the back of the passenger footrest needs to be bent to the correct shape and then bolted on. This is a bitch and I still need to do it. My buddy and I tried for about 30 mins. Be forewarned...
After that, its time to mount the license plate relocation kit kindly provided by Quat-D. This thing is beefy and in my mind a bit over-built (heavy), but that area receives alot of vibration.
Here is also the only place where Quat-D made a mistake in my mind and thats not including proper bolts to mate up the the subframe. They were very small barely larger than the holes and too long would have rubbed against the frame. Nice bottom plate hides the unsightly bolts and voilá you a nicely relocated licensee plate. Another item here that could be a bit better would the be the same kind of plates that the Termi kit has. Even though the plate is moved up to fill some of the void left by the lead-filled stock can, it looks a bit hollow.
So fire it up!
Holy Crap!

This system sounds beefy! Here is a
video that really doesn’t do it justice. I can’t wait to meetup with some other Hyper owners with Termi’s to compare. From my recollection it sounds a bit louder and more gravelly, which makes sense since it has fewer bends to travel though.
Overall I am quite happy with this system. And looks forward to terrorizing the city with its deep-rich sound.
More pics can be found on my flickr page.
Here is my list of pro’s and cons:
Pros:- Light (13.44 lbs lighter than stock system)
- Fantastic build quality
- Amazing sound, car alarms will fear you on down throttle!
- Inexpensive!, almost 1/3 the price of the Termi system, although it doesn't come with an ECU
- Unique, everybody else I see has the Termi full-system.
- Increased cornering clearance
Cons:- No english instructions
- needs bolts that will correctly mount the plate relocation bracket
- Tight tolerances make it a timely process to mount
- Really could use Termi-style side-cover to clean up the tail end.
