Congrats on the new exhausts guys!
Topic of ECU mapping has been covered 1000 times on the forum but it’s always worth clarifying.
There is no such thing as a “slip-on” for the Scrambler. Slip on means just the muffler changed, with the catalytic converter and headers staying the same.
The scrambler only has a 2 part exhaust. The Catalytic converter is built into the muffler section of the exhaust. By swapping to a new exhaust, you’ve removed the catalytic converter (de-cat) and significantly altered the exhaust flow of the bike.
I think it’s really misleading that Akra sell this as “does not require ECU map.” Because it’s basically a lie.
While the bike will possibly run ok without a map and plenty of people never bother, it won’t run optimally and on a lot of bikes (my own included) it will run like crap without a map. In most cases, you’re likely to actually lose power.
The main point I’d make though, is that dropping £1000 on a fancy Akra exhaust will make the bike sound fantastic and a lot lighter but without a matching tune, you’re missing 90% of the benefits.
Removing the cat allows the bike to breath WAY better when tuned correctly and not only will you see good power gains, the throttle response and smoothness of the engine is much improved.
Don’t skip the tune! Throw in a K&N air filter, and get your bike a custom tune on a dyno. You’ll really feel what that exhaust is doing for you and have a much better (and happier) bike!
