Lowside with termi 2-1 system... anyone?

[EarthBM]

Tried to read through the exhaust threads and my brain exploded from info overload. (eg this beauty Exhaust alternatives)

So I will just formulate the question:

Has anyone lowsided on the right with the full 2-1 termi system? What's the damage to the can?

Or is there a full system (less weight/mo'power and rideability) with a single (less weight) underseat (can use bags and more crash'able) exhaust?

Yep.

Quat-D's 2-1 system is not only two-into-one and has a single can, it has a gorgeous titanium can... Not to mention some of the most beautiful welds I have ever seen and a nice magnesium cap on that aforementioned can. It also routes far lower than other brands which doesn't hurt the center of gravity, and though it may seem a bit esoteric to mention it does stay closer to the middle of the motorcycle lessening the polar moment of inertia...

You know, that "mass centralization" thing Honda is always talking about...

You can find Quat-D's Hypermotard system here:

http://www.motowheels.com/italian/myproducts.cfm?parentcategoryid=660|Ducati%20Exhau st&productID=5776&showDetail=1&categoryID=891|Hype rmotard%20Exhaust&vendoridtodisplay=0&filterFor=&c ollection=168|European%20Motorcycle%20Parts










It also has an interesting mount for the can, in that it mounts it well inside of the passenger peg mount. Well inside. I have one on my Hyper and it mounts the can so far inside I cannot imagine how the can can hit the pavement unless the entire passenger peg mount and peg were ground away. I suppose the tip could hit in the right kind of crash, but IMHO this one is much less likely to touch down than the Termi.

I shopped around a lot for an exhaust system after I got my Hyper, and I was continually stunned by nearly all mounting the muffler way up high. The muffler location is one of the only things I don't like about the Hypermotard. I have never understood the logic of putting one of the heaviest components on the motorcycle as high up in the air and as far away from the center of mass of the motorcycle as you possibly can on a street bike... Not to mention putting one of the hottest possible pieces of the bike right under the seat.

Sure, you can say it's a nice styling lick, or that some race bikes route the exhaust there to try to get some hot, high pressure exhaust gas to lessen the negative pressure area behind the bike at speed... but race bikes have nice, light pipes - not big, heavy, hot mufflers.

When I saw the Quat-D I knew I had foound the right pipe. You will have to be a bit creative with remounting your license plate and signals. Quat-D does provide some pieces for you to do this, but it uses a lot of the stock parts and it was less than an ideal solution for me. If I get some time I will post some pictures of my solution.

Anyway, you might want to look into the beautifully made Italian Quat-D exhaust system - http://www.qdexhaust.it/

Did I mention that Quat-D makes Ferrari's exhaust systems?

Hope this helps.

This is very nice. Did you get a chance to check their 7kg weight saving claim when you installed yours? I am surprised, given that that it retains the catalizator, exup mechanism, etc. and yet is the same saving as the Termi 2-1.

I especially like it because it allows you to get creative with the whole tail (as in, make it even smaller?)

Did you change stock ECU?

Also, can you take the rear wheel off without touching the muffler?

When you make pictures of your install, could you make a profile short from the back?

The Quat-D system does NOT retain ANY of the stock exhaust components... Not the catalytic converter, not the exhaust flapper valve, nothing. It is a complete exhaust system, front to back, head to exhaust tip. Beautifully welded and fabricated stainless steel headers leading to that gorgeous double-tapered - it starts out round at the header-muffler junction and then morphs and expands into an oval at the exhaust tip - and tucks in much better and tighter than any part of the stocker. It even eliminates a bracket under the engine, not to mention the catalytic converter, exhaust flapper valve, O2 sensor (though it has a bung to run it if you want), a bunch of heavy bracketry under the seat that hung the stock muffler, etc.

It also has high-quality bungs in each header pipe - very conveniently located, BTW - for exhaust gas probes if you have access to an exhaust gas analyzer...

No question in my mind the Quat-D Hypermotard system saves 15+ pounds (7 Kg). Feels like more...

As for the ECU... Yes, I currently have a DP Termi 2-1 "Race EVO" ECU installed in place of the stocker, along with a DNA air filter and GDS air box lid. So far I have run it just like that, though I have a Technoresearch VDST set-up to hone it a bit further if necessary. I also have a DP "Cams" ECU stashed in the toolbox if I decide that's needed...

I got both the ECU's from members here on the board.

I have to be honest, I have only a few miles on the bike since I installed the exhaust, filter, box lid, ECU, etc. In fact, the bike is now back on my lift half disassembled while I figure how I want to do some other tricks... I will say it runs what feels like 200% better with the Quat-D and other mods. Revs quicker and smoother - like all bikes do when you toss a catalytic converter - and pulls a LOT harder.

People may say I'm nuts, but I swear you can feel the handling difference in getting that weight off and lower, lowering the center of gravity and lessening the pendulum effect of having that stock muffler increasing the polar moment.

Besides, even with having to find a DP ECU, a DNA filter, a GDS airbox lid, and some other knick-knacks for the license, etc. I still have nearly a GRAND less invested in the whole rig when compared to the Ducati Termi 2-1 kit...

That'll buy a lot of other bark, bite, and bling, eh?

And I think the Quat-D both looks and works better... Just my humble opinion... YMMV.

Hope this helps!

This does help, thanks!

I only thought that QD came with cat and exup because it said that it was Euro 3 homologated on the website.

Looks sort of blah in my eyes, and Ducati would never accept that design because it takes away the killer view of the full rear wheel exposure which is about 50% of the bikes good looks, now you have a pipe blocking that... just my opinion...

I fully understand... Different strokes for different folks. That's why I'm glad we all have choices, and that the aftermarket provides with so many interesting and wonderful options to allow us to each make our own motorcycles unique and personal.

For me the adage "form follows function" has always been an important guideline. Street exhausts that exit out the tail don't make any real logical sense... Sure, they're an interesting place to place the exhausts from a styling standpoint, but they have a lot of drawbacks, like the raising of the center of gravity and increasing the polar moment of inertia I mentioned. Both are bad for handling. Sticking one of the hottest components on the motorcycle pretty much under the seat doesn't seem to be much of a good idea, either...

BTW, I did forget to mention earlier that you most definitely DO have to remove the titanium can of the Quat-D system to remove the rear wheel on the Hyper. That's really not a big deal, though... One bolt and two springs and the can is off. Damn near takes longer to describe the process than it does to do it.

you can also get a muffler slider from https://ssl.perfora.net/www.advanced...dex.shopscript

I don't really like the look of them, but don't want to face the day when I ruin a $2k exhaust system with one mistake.
