1198 Termi exhaust dyno test. - Ducati.ms

Spent the day gathering some test data on Termi exhaust options for 1198.
I did them all today on the same bike and all configs are fully mapped to be able to evaluate what the exhaust isolated does and where.

The DB-killer referred to is the standard Termi item and it is not a well designed DB-killer, I just put them in for shits and watch them kill the top end, and they certainly did.

On 1098 the full termi doesnt do anything, but on 1198 it actually helps.
For a street bike I personally would go slipon, but for track bikes the full is the option I'd choose, however at the money it comes at there are more efficient ways to increase power.

All the configs are fully mapped and they are all heat sunk, so I would say they reflect what the pipe setups actually do.
Deviations below 5200 rpm is just from me opening the throttle randomly fast, I see no point lugging the engine below 5k.

Heres the chart, read whats what in the pic

Good info. & it's nice to see a decent HP gain with a full system. From what it looks like on the graph (blue & red lines) is the power band never get's any smoother. Most of the time you'll see a more linear power band with full mapping. How is it on the road ?

This is just to evaluate for this customer, which is racing, what config to go for, and in racing the actual numbers count.
Mapping is more about part throttle crisp than anything else, yes.
And fully mapped part throttle can make you feel like there is a lot more top end although there isnt.

Well done and pretty comprehensive Tom! Like you stated, it's not the number but how it performs. I find these types of data very interesting...I'm sure there will be some protest when owners find that their 1198 w/ a full system Termignoni doesn't make 180rwhp.....

Someone please correct me if I'm wrong but I was always taught that it's not the amount of HP you have but how it's put to the ground. Now I was building cars at this time but I'm sure the same applies for street bikes. So a little less HP but more torque is better then more HP and less toque?? Correct? I know that everything together plays a big part, Tire choice, temps, pressures and so on.

Youre right, its more about spread of torque than anything else, top numbers from a quick peak is pretty useless, agreed.

Depends on how much you can get the full exhaust for and your personal preferences of what character bike you like etc, theres not a simple answer.

Say you have a completely untouched bike, then full system is a waste of money until you have the basic settings done, cam timing checked etc.

Slipon, a good set of pistons, cam timing and mapping will easily outdo a a full system untouched bike everywhere, at around the same money or less.

I see it as a list of priority and full system is a bit down but not pointless on the 1198. (On 848 and 1098 there is no point at all.)

And I only discuss power, full may be lighter and you may want it just because you feel good about it, I have no problem with that at all, I have plenty of those

Hi, I have a 09 1198s that has the Termi kit, Carbon slip ons, race computer, air filter.
I just picked up the header system for it, is there anything I need to do when I install the headers? Was told everything is done just install the headers. The main reason is to get rid of those HOT ass cats. Thanks for the info.

I would think nothing at all. Even though your Termignoni ECU is set for a slip on system and less restrictive filters it should suffice for the full exhaust. The only sure fire way you'll know that the exhaust is performaning at it's optimum is to have it professionally dynoed and tuned. I doubt it would need another ECU.
Tom - after having my crank properly balanced it really is a shame how poorly set up a Ducati comes from the factory. I'm sure there are many that are set up well, but after feeling how smooth my 999 is after crank balancing I was pleasantly surprised, no shocked! The issue is the cost to do this, however the benefits are great.
