Most "performance" exhausts on modern, electronically controlled bikes, actually reduce horsepower by a couple percent unless the ECU is also modified.


If you do reflash the ECU, it can increase HP by a couple percent.


Most people who replace the exhaust say they can feel an increase in power, even on bikes with stock fuel programming that have actually lost power.
Realistically, Nobody can feel a 5% change in power, up or down.
And that said, I intend to add aftermarket exhaust. The biggest difference from reprogramming the fueling is drivability in lower RPMs, and that can be felt!

Yeah, I think the real beneficial reason to have the open exhaust is to get that 'Racing' ECU map applied to your bike. That way the stuff that was thrown in to meet worldwide emissions requirements will go away and make the throttle more user friendly from take-off.

Speaking of which, does anyone know what they did to this engine vs the Monster 796 engine in terms of differences that affect the power and torque?

I know the bikes are physically geared differently (I think one more tooth on the front sprocket on the Scrambler) but is the compression different, different cam profiles, etc???

Because I've seen modified Monster 796 that make quite a bit more horsepower than delivered from the factory (at least from what people are saying.)

For me, I want to be more like that guy that has 238k miles on his Monster though. Whatever is more reliable is what I want done to the bike. People were power wheelieing the media review bikes with the stock muffler. I'm sure it's fast enough for my needs.

Typically to get increased power output, one needs to work right from the intake all the way to the exhaust and also modify the fuelling parameters in the ECU, as you would probably know from your cars. The only difference here being that people don't usually add intake manifolds.

It's early days for the Scrambler and we wouldn't know for sure until someone plugs in a modified bike to a dyno, this is the official line from Ducati on these exhausts:

Sport-Line:
Thrilling sound with removable db-killer and full power delivery thanks to the dedicated mapping; this steel silencer with up-map key makes for an exciting ride right from the word go.

Evo-Line:
Racing style, urban character. This steel exhaust with catalytic converter meets the need for an “easy” bike, without giving up its sporty attitude.
I'm guessing that in the case of the Sport-Line there is a minor power bump, but more importantly, how this power is delivered across the rev bands is altered by the accompanying ECU update, aka the power delivery curve. This would probably result in a more 'sporty' response which may or may not be felt by the rider but can definitely be 'heard'. ;)

Ok, everybody considering the termi race exhaust read the bolded text above over and aver again. The race termi I had installed yesterday did exactly that. No noticeable improvement in performance but I definitely felt that low rpm performance had been adversely affected. Sounds strange but it felt like the engine was lugging at low rpm. On top of that the muffler made the exhaust much louder but did not change the essence of the engine note. For example I love the sound of the decompressing engine when you let off the gas. That sound didn't change at all. But when you twist that throttle you will definitely get everyone's attention. Above all, think about that bolded part above before you fork over the $1500 like I did.

I am surprised you find it not to your liking at lower revs as I have seen others saying it makes the bike smoother after having the race slip on added with the upmap to ECU

Biggest differences are other cam profiles(i heard ,there are 11 degrees cams like the 4 valve engines from Multistrada have) and the single throttle.

In my opinion it is a really good engine for country roads,even riding in the city is comfortable.This is a pain with i.e. the High-performance 4Valve engines from Ducati.

At the moment i dont miss more power,but my dream-engine for the Scrambler: The air-cooled 1100cc from the Monster with the mild cams,single-throttle and tons of torque.

I was thinking that that was what JustKip was saying too but now that I have re-read his post it looks like he was saying the opposite. So I guess I am alone in thinking the termi upmap decreased low rpm performance and everyone else thinks it improves low rpm performance. I only logged about 20 miles after the upmap but that is what if felt like to me. I even took the bike back to the dealer and he reloaded the upmap again but there was no change. I don't know what to say other than it must be some freak anomoly or I am just not interpreting the feedback from my scrambler at low rpm properly. The bike did stall twice on me in those 20 miles which is unusual and not something I could misinterpret. I will be paying close attention to what is going on at low rpm's from now on and will report here if I find anything of import.

All of the adaptation stuff in the computer may not be set in stone in the ECU yet, so it might get better after more miles and more types of riding situations?
Maybe the ecu does need to adapt. In my own experience when removing the cat and letting the engine breathe better I have always had a positive result. Yes the sound is louder/deeper but at low revs I have always found the bike to run smoother too hence why I find it at odds that the Termi race slip on has made things worse in this one case. However every time I have removed the cat I have always added a K&N filter at same time which I intend to do for the scrambler too

Just bumping this thread to get updates from current termi slip on owners. What's it feeling like now vs stock? I'm seriously considering it but haven't quite made up my mind yet. Testimonials appreciated.

After 2,500 well ridden kms with the Full Throttle shotgun Termi, I pulled the trigger on the Termi Race slip on.

There is absolutely nothing wrong with the FT Termi. It has the best sound I've ever heard out of a stock pipe and many who I have ridden with could not believe that it's OEM because of how great it sounds.

The only reason for spending the big money on this exhaust for me, after carefully weighing my options, was 1) the louder, deeper sound (which I particularly enjoy from the resonator-tuned Termi race version and 2) the accompanying ECU map as fueling is critical for me on this bike and I am not interested in any custom tuning.

I went about switching my exhaust in an un-conventional way: rode my stock FT to the dealer, purchased the Termi slip on, had them flash the ECU, then rode back home (60km) with the FT Termi and Race map (and the slip in its box, strapped to the back of the FT on the highway!).

There was a slight difference with that map running on the FT Termi. Bike had a bit more punch and revved a little quicker. Probably a richer map which the stock system didn't seem to mind.

Then, I spent about 2 hrs installing the "slip on". You must think I'm a retard right? 2 hrs to install a slip on?

The thing about this set up is that it includes a separate chamber resonator (most other slip on a don't) and so the "slip-on" is actually two separate pieces. That became problematic when trying to line everything up with the stock headers and connector pipe, so I basically had to take most of the exhaust apart to get the jigsaw puzzle to fit together and get all the mounting holes and flanges to line up.

Have ridden about 100km of mixed terrain with the Termi Race slip-on and here are my thoughts so far:

1) The sound is seductive.

It just feels so right. It's a **** shame that this bike doesn't sound like this from the factory (legalities, I know) but it just makes an already-great machine that much better. With the baffle out, it just sounds like a proper motorcycle. Not ear-bleeding loud, just present, in a "don't screw with me" kinda way. With the baffle in, it made a really annoying whistling sound and so that baffle has been stored. Permanently.

2) Power is definitely up.

I'm not just talking butt Dyno here. My test for whether or not a bike is making more power is always the power wheelie. Stock, the bike could raise a little in first if I hammered the gas. Now, it comes up more easily and I can get it to lift in 2nd with a little help from bumps in the road. Fact, not opinion.

3) Fueling is 95% of what it used to be.

This was a really important factor for me as I have ridden other bikes with this motor (monsters) that have other brand slip on's and their fueling was affected negatively. I'm happy to say that fueling is nearly identical to stock (read: VERY good for a Ducati) with only a slight stumble that I notice around 2k RPM.

4) Heat is also up.

This is a subjective measure but in traffic, the bike feels like it gets hotter, faster than with the stock exhaust. This is not uncommon when running free-flowing exhausts and it's not a deal-breaker for me, but still worth noting (see comments/solutions in "ball roasting" thread).

All-in-all, it was worth the $ for me and I lives up to my (high) expectations. There was also a weight savings of (what feels like) about 10lbs. I'm not going to say that you can necessarily feel it but it's easier than me trying to lose 10 pounds ;)

Anyone do a dyno run to compare before/after Termi & remap?
Termi race pipe and Ducati supplied remap will give you about 3hp over stock. Nothing to write home about - but as stated - sound is much improved.

Termi race pipe and a better remap will get you around 6+

Termi race pipe, freer flowing intake, better remap will give around 8hp over stock.
