FAQ B 1
How can I clean Storm exhaust system?
First, before cleaning the exhaust, always let it be cool to the touch. For cleaning, use a soft cloth or a sponge with lukewarm water and a non-abrasive cleaning product. For instance, car shampoo acts properly. Stainless steel and titanium surface can be cleaned regularly with a penetrating oil spray. A light buffed layer of this spray will make maintenance easy. Carbon filter can be cleaned with a soft clean cloth. Do not use a high-pressure washing plant or a steam cleaning plant to clean the exhaust surface.
FAQ B 2
When do I have to replace the packing material of Storm exhaust?
Through long term and/or high performance use, the packing material of your exhaust can degrade over time. Your Storm Dealer can advise you on this repacking procedure. Possible symptoms are an increasing sound level and exterior discolouring. When this occurs we recommend that the exhaust muffler be repacked immediately to avoid it degrades further. Possible discolouring of coating due to degraded packing is not included in the terms of our warranty.

FAQ C 1

Storm exhaust systems are specifically designed for a specific model; any compatibility is expressly indicated. Storm advises against assembly and/or adjustment on models which are not provided for. Otherwise, the warranty and the type-approval, specifically provided for every motorcycle model, will not apply.
FAQ C 2
Which are the down pipe diameter and the muffler size for my motorcycle?
Diameters and sizes change from one model to the other one. We prefer not to spread this kind of information. Anyway, they are specifically designed and chosen to reach the best performance in terms of power and torque.
FAQ D 1
Is the registration of changes required on the registration document in order the type-approval be effective?
No. The type-approval number only, stamped on the muffler, is required to attest the type-approval of the muffler. Furthermore, Storm delivers with the kit a relevant certificate to produce in case of check.
FAQ D 2
I missed the type-approval certificate. How can I have a duplicate?
You simply have to get in touch with the customer service at email@example.com and specify your motorcycle model as well as the type-approval code stamped on the exhaust. The copy of the certificate will be sent immediately by e-mail.

Storm systems are specifically designed to operate at their best without any change. All data we issue are obtained in this configuration, if not otherwise indicated. If an additional control unit with the mapping concerned is used or an after market filter is installed, the power delivery could be improved as well as the general performance of your motorcycle.
FAQ E 2
How much increase in power can I expect from a Storm exhaust?
Storm exhaust are subject to bench test before being marketed. It is essential to underline that these tests are carried out only on production motorcycles where the original system only is replaced with a Storm one. Generally speaking, all results of bench tests take shape in an increase in torque and power where the value depends both on the motorcycle which is tested each time and on the special conditions in the lab (atmospheric pressure, humidity, air temperature, etc.). These results are published on our website in the form of graphics (dynochart) where torque and power curves of Storm exhausts are compared with those of original exhaust (stock).
