One of the first modifications made to a motorcycle is to change its exhaust. Silent, complete line, a multitude of brands like Scorpion or Yoshimura offer adaptable elements in a more or less racing style. All you have to do is choose…
SILENCER OR COMPLETE LINE
In addition to the legal side with often complete lines reserved only for use on the track, your budget will also tip the scales towards a complete exhaust or a silencer which will take place on your original collectors.
The transformation will be done without difficulty if you opt for an adaptable solution close to the origin. If this is not the case, with for example a double exit or exhausts migrating under the saddle, it will not be necessary to rush but to take into account various factors such as the rear footrests, the heat released by the silencer or even the integration of the license plate.
Most often the exhausts are supplied ready to fit with everything you need (screws and seals included) to simplify your life.
LOOK, POWER OR SOUND
The power gain is variable, find out beforehand by consulting the mapping curves (power and torque). If most of the adaptable exhausts are compatible with the original injection settings, changing the exhaust can make you lose homogeneity with the key holes, cuts, which will then require a specific mapping for good engine management. Again find out if the item you want to add is compatible with your bike and the right vintage. The purchase of a reprogrammable box of the GET type (adapted mapping offered as standard with the possibility of making one specific to your needs) will be the solution to your problems.
Whatever your option one thing is certain, you will benefit from a gain in weight, volume and look. The sound will also be harsher while remaining approved if you keep the chicane (or removable dB killer) mandatory for road use. Remember that the removal of your catalytic converter is to be avoided in order to comply with current requirements.
To be entitled to the best this new exhaust offers, head to the workshop with the production of a tailor-made map, but all that at a cost.
STAINLESS STEEL, TITANIUM OR CARBON
Afterwards it is a question of taste and style with different materials (stainless steel, titanium, carbon) more or less heavy, restoring or not the heat emitted. If carbon is very efficient on the thermal side, it will generally have a shorter lifespan. The rock wool (acting as an acoustic damper) will also have a limited lifespan. Good news, it can be replaced if your slip-on is equipped with rivets or screws. Also remember to add a muffler protection , a detail that will allow you to preserve your exhaust in the event of a fall.
