Termignoni slip on and horse power.

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'.

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

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.

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
