Testing by the shops in my area indicate that the Termis provide an increase of 8% in peak horsepower. The 70mm header seems to provide a 1-2% increase in peak power. Running is better too, since the DP ECU maps are non-EPA approved.
If you look on Ebay you'll see dealers selling Termi silencers and full exhausts for the bike at "Best Offer" rates. This is one way to find out what discounting is possible. Another thing to think about when looking for a discount is install of the silencers is a 3.5 hr. book rate job and installation of the full system is a 4.5 hr. book rate job. Comments by the people who have done the installations, seem to indicate that it takes practice to do the job within the book time. If you do not intend to do the job yourself, many dealers seem to be willing to do the installs for free as part of delivery and setup and if you've already taken delivery, it is worth seeing if you can get a discount on installation.
Another alternative to get performance and running improvement is to get a PCV when they become available or to get your ECU remapped when your local tuner(s) figure out how to do this. The 1199 seems to suffer from EPA driven fueling. This is another cost factor to consider when buying silencers or a full exhaust as anything which provides any real performance improvement is going to require changes to the fueling map. The cost of a PCV or ECU remapping, should be added to the cost of any silencers that do not include a new ECU map, like the map included with the Termis.
Is that an 8% increase with the slip on's?? Seems kinda high for just the slip on's.
I ended up getting the slip on's. Had them installed by the dealer while the bike was in for it's 600 mile service. Louder than stock, but not by much (I'm going off what I hear, I haven't had it measured). The tone is deeper, i love the new sound. Also feels like there is much more torque in the lower rev range. I followed the manual and kept it under 6,000 for the break in, so I can't comment on what the power felt like above 6,000 before, but man, you can really feel more power kick in above 6,000.
I've read a lot of posts from people saying they were disappointed by the lack of low end and mid range torque. Wondering if these people are forming this opinion by just reading posted charts or from experiencing the bike on the road. I'm coming off a '08 1098 with slip on termi's, race ECU and race air filter, and I can say the 1199 feels noticeably faster. No difference in torque in the mid range that I can feel, but the 1199 feels like it has endless and effortless power way up the rev range. You almost need to train yourself not to up shift as you hear the revs climb. On the 1098, hearing that amount of engine rev would prompt me to up shift, but on the 1199, you can just keep climbing AND gain more power.
A friend of mine has a tricolore being picked up in a week or so. He will have the full system. I can't wait to actually experience the difference between the full system and the slip ons.
