Looks like you have an 1199. Main exhaust options are termi's, akra, and I had Austin racing on my bike. The reason I went the route I did was that they were different from the normal systems. To me they look and sound better. I feel that with any full system a tune has to be installed too, not for power gains but to help it run smoother. Any of the above full systems with a tune are gonna run you in excess of $4000.00 you can get termi slip ons for around half that, perhaps less if you buy used. As you have limited tools and experience it may be wise to let a dealer or bike mechanic do the installation for you.
If money is no object go for the one you think looks and sounds the best. Don't get too caught up in Hp numbers as pretty much everyone on here is not able to push the 1199 to it's limit. Sure, we can push them to our limits but they are usually far short of the bikes limit.
Good luck and enjoy the bike.
