I'm getting that same exhaust, love the look and sound of it! A tune is not required. As stated by Bat-1, Toce offers a tune, and if you do the tune at the same time the exhaust is purchased they also offer a discount so if you decide to go with a Toce tune I'd contact them and ask if you can get the discount after purchase since it was purchased as a gift. Without adding a high flow air filter, you're not going to see much gain even with the tune.
I'm planning to get a high flow air filter and a tune, although I haven't decided on a Toce tune or taking it to a race shop that will dyno and tune my bike specifically for the performance I want.
