KLR650: Exhaust

Another great combination package - the FMF Powerbomb header and Powercore 4 Muffler.

The Powerbomb header promotes better flow by allowing a small expansion of the exhaust gasses improving scavenging. The 'bomb' also acts as a pre-muffler taking the edge off of overall sound levels.

The PowerCore4 muffler was developed to increase the horsepower and torque throughout the entire power curve and give you a noticeable power increase that is very usable and beneficial, no matter what your riding style or ability is.

Some of the features of the PowerCore 4 include: space age internal packing for maximum packing life; hi-flo modular end cap; internal shape of core uses hi-flo technology; enhanced sonic evacuation provides for higher flow and increased power and removable spark arrestor.

The FMF Powerbomb and Q4 Muffler are legendary in the exhaust market.

The Powerbomb header promotes better flow by allowing a small expansion of the exhaust gasses improving scavenging. The 'bomb' also acts as a pre-muffler taking the edge off of overall sound levels.

The Q4 muffler employs intricate chambers, baffles and proprietary multistage packing material making it the best performing quiet muffler available with a sound output of 96dB; with most models below 93 dB. It is constructed from aircraft grade aluminum and high strength stainless steel.

The new DG RST (Reduced Sound Technology) muffler is the quietest DG muffler and is designed especially for dual-sport machines (Just 89db @ 3200 RPM). A new baffle design dissipates sound waves reducing noise output in a very efficient manner. This new design also stretches out the time between muffler repacks. Included is a Stainless Steel mid-pipe, USFS Approved Spark Arrestor and a new Aluminum end cap.

You may want to consider a new exhaust gasket that goes between the header and the muffler.

DG Performance exhausts help your engine breathe better, resulting in increased throttle response, power and torque.

The V2 Series Slip-On muffler features:

• Lightweight aluminum body
• Stainless steel inlet tube
• TIG welded components

No repacking required. The LeoVince X3 Enduro is made with TIG welded stainless steel internals and aluminum outer shell. It features a semi-direct chamber design that is maintenance free. It's quiet too! Our own in-house testing showed a 84dB sound level using the USFS J1287 testing procedure. That is a bit louder than stock but significantly quieter than other aftermarket mufflers. It includes a certified Spark-Arrester. This muffler requires a stock muffler joint gasket when used with either the stock headpipe or the FMF headpipe.

The FMF Powerbomb is a four stroke header pipe unit that has a unique bulge precisely located in the header system. A "pre-muffler" of sorts, the Power Bomb actually lowers sound output because it creates more surface area to absorb the sound medium (exhaust). The surface area of the perforated core lets the sound exit into the absorbing material (steel wool packing) and then allows the air to expand, cool and ramp back up with the higher pressure air. The result? The FMF Powerbomb is instrumental in reducing the decibel level on any four stroke and because of the expansion and contraction on exhaust through the system, the flow has been increased by nearly 10%. That means more power throughout the range.

Features:

• Tuned for bottom to mid performance
• Powerbomb headers are the front runner in performance headers
• Designed for full service access to oil filter

• Reduce exhaust sound by one to six decibels
• Options for DG V2 & RST and for the older "O" & "R" Series mufflers
• Easy installation; remove rear end cap and place Quiet Core in front of the spark arrestor
• Smaller diameter inserts are quieter but more restrictive; larger inserts are less restrictive but louder
• 1" Not recommended for RST
• Each size is sold separately

This Quiet Insert comes stock in all new FMF Q4 mufflers. If you lost yours, this is the replacement you need.

It will fit Q4, Q4 Hex, Powercore and Powercore Hex mufflers.

It will reduce the sound rating of the Power Core models, from about 99db down to about 96db.

Please choose the correct Insert for your muffler. If you are unsure of the year that your muffler was manufactured you can easily identify visually which insert you will need.

This is a new gasket for the cylinder head - head pipe junction. Installing a new one with your new header will ensure a good seal and no exhaust leak.

This is the gasket used between the header pipe and the stock muffler. This gasket is not needed for aftermarket mufflers!

Protect your head pipe from rock damage. This stainless steel spine clamps to your head pipe to add a layer of protective armor between your vulnerable pipe and those nasty rocks or logs. Fits the stock headpipe. Will fit the FMF head pipe with the addition of larger clamps.

If your aftermarket exhaust is missing heat shield mounting points for this is the easy fix you’ve been waiting for. Includes one stainless steel mounting bracket with M6 threaded nut, and one stainless steel hose clamp.

Fits exhaust approximately 1.1inch-2inch diameter. Trimming may be required for smaller diameter exhausts.

The Chilly Exhaust Heat Shield is the most effective heat shield on the market. The innovative three piece design consists of a top shield attached to 2 rails with rivets and spacers. This reduces the contact area and slows down heat transfer. They have incorporated a patented, insulated reflective blanket on the underside of the shield to reduce radiant heat transfer. The included stainless steel clamp makes it simple to install.

We highly recommend a heat shield if you run soft luggage without hard racks.

FEATURES:

• Solid Top Shield - The logo is laser etched and there are no cutouts on the top shield. This prevents radiant heat from passing straight through to your luggage.
• Side Rails - By isolating these with spacers the heat conductive surface area to the top shield is reduced and slows down heat transfer.
• Radiant Heat Shielding - The reflective insulated blanket on the bottom of the shield is the real hero. This patented material won't be found anywhere else in the motorcycle industry. 
• Stainless Steel Clamp - Slots have been provided in the side rails to make installing as easy as it gets.
• Brushed Aluminum - Lightweight and looks nice.

DIMENSIONS:

• Length 7.5" (190mm) x Width 3.5" (76mm) x Height 1" (25mm)
• Clamp fits any exhaust 3.5" - 5.5" (89mm - 149mm)
