SLIP-ON EXHAUST SYSTEM
BMW G 450 X Enduro (2008 - 2010)

DESCRIPTION

The Akrapovic Slip-On system delivers an excellent combination of quality, performance, visual enhancement, weight reduction, easy installation and affordability. The Akrapovic Slip-On is designed for two markets; in the US it is available with an approved spark arrester, and for the EU and other non-US markets it comes with a noise damper. PERFORMANCE Measurements of the Akrapovic SLIP-ON system on the BMW G450X (with muffler insert): Power & Torque: Up to 35000 rpm the Akrapovic Slip-On essentially follows the stock power and torque curves. It shows its true colors above that range, where it delivers significant increases to both power and torque. Max. increased power of 3.1 HP was measured at 5900 rpm. At the top of the rpm range the Akrapovic curves again follow the stock power and torque curves. CONFIGURATION The system is composed of a titanium link pipe which is welded to the muffler. It is attached to the stock header assembly with a sleeve joint secured with a metal clamp. The hexagonal shaped muffler is the offroad design with a titanium outer sleeve, inlet cap and inner perforation. Outlet cap is made of carbon-fiber. The muffler is attached to the frame using an Akrapovic carbon-fiber clamp. In the US the system is available with an approved spark arrester, and for the EU and other non-US markets it comes with a standard noise damper.

Final installation: 1. Clean grease spots: a. Muffler titanium outer sleeve: use a soft cloth sprayed with a multi-purpose spray lubricant (WD-40 or equivalent). b. Muffler carbon-fiber outlet cap: use a soft dry cloth. c. Stainless steel link pipe: use a soft cloth sprayed with a contact cleaner, then wipe with a soft dry cloth. d. Titanium inlet cap and welded link pipe: use a soft cloth sprayed with a multi-purpose spray lubricant (WD-40 or equivalent). Cleaning will prevent spots from burning onto the surface. Do not use aggressive chemical cleaners, because they can damage the sticker.

Check the operation of the brakes and suspension. Make sure all the bolts are sufficiently tightened. In case the exhaust system touches the cowling or other parts repeat the adjustment of the exhaust system or contact your authorized dealer. IT IS NORMAL IF WHITE SMOKE COMES OUT OF THE MUFFLER ON FIRST OPERATION. DO NOT STAND BEHIND THE MUFFLER ON FIRST OPERATION. DO NOT USE AUTOMOTIVE WHEEL CLEANERS OR ANY CLEANING PRODUCTS WHICH CONTAIN ACIDIC ADDITIVES TO CLEAN AKRAPOVIC EXHAUST SYSTEMS.
MAINTENANCE OF THE AKRAPOVIC EXHAUST SYSTEM 1. Clean the titanium exhaust components with a multi-purpose spray lubricant (WD-40 or equivalent), carbon fiber exhaust components with soft and dry cloth and stainless steel components with soft cloth sprayed with contact cleaner, then wipe with soft and dry cloth. Do not use aggressive chemical cleaners, because they can damage the sticker. A change in the color of the exhaust system is normal due to the high temperatures. The wearing out of the muffler silencing material depends on the type of the engine and riding style. Contact your dealer/serviceman if visible changes appear on muffler's outer sleeve or the noise level is increased. Periodically make sure all the bolts and springs are sufficiently tight.
