Exhaust

Don't get burned! Giant Loop's ingeniously simple and effective exhaust shield protects bags and bodywork from heat damage. The Hot Springs Heat Shield helps avoid the meltdown, preventing bags and side panels from touching your bike's exhaust. It's the lightweight, universal heat problem-solver for virtually any motorcycle exhaust system. Backed by a Limited Lifetime Warranty.

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)

A highly refined blend of aluminum, copper and graphite lubricants. Use during assembly to prevent galling, corrosion and seizing due to weathering or chemicals. Anti-Seize assures easier disassembly. Temperature range: -60°F to 1600°F (-50°C to 870°C). Salt, corrosion and moisture resistant – ideal for marine use. Meets Mil Spec #907E.

The PowerBomb header promotes better flow by allowing a small expansion of the exhaust gasses. The 'bomb' also acts as a pre-muffler taking the edge off of overall sound levels. Includes clamp-on mounts for the stock heat shield.

For FMF mufflers only

The science behind the MegaBomb header may be FMF's greatest engineering accomplishment to date. You can bolt on a MegaBomb with an existing FMF Racing slip on for as much as a 3hp boost, plus the MegaBomb actually reduces noises levels by as much as 1.5dB. The MegaBomb technology is evolved to produce more low end to mid range gains as well as broadening out the mid to top end power gains over stock. MegaBomb is the next level technology you can have today.

• Produces long header torque and short header over-rev
• Reduces sound output as much as 1.5dB
• Increases output from stock motor as much as 3hp
• Stainless Steel Construction for durability

For FMF mufflers only

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

• The ultimate power booster featuring exclusive Ti-Metal construction
• Improved bottom to mid-range power
• Produce the low end of a longer header and the top end of a short header
• Less susceptible to damage than a long header
• Runs well with sound-restricting mufflers; effectively reduce sound output by as much as 1.5 dB
• Substantial power increases everywhere
• Constructed of extremely lightweight materials

X3 EVO represents the off-road evolution: LeoVince has combined all its experience in the off-road world with cutting-edge materials and Italian design, enhancing freedom in its purest form.

The X3 EVO body is made of AISI 304 stainless steel with TIG welds handcrafted by specialized operators, to guarantee long-lasting performance. X3 EVO will allow you to face the most extreme environments and conditions because it does not fear water or mud, nor wear over time.

The LV logo is their tribute to a motorcycle culture that we have loved for 70 years and is laser etched on the body of the exhaust: it is as endless as their passion.

They manufacture the end cap in 100% real carbon, with their special 2x2 twill carbon fiber, specifically designed to resist high temperatures and make the X3 EVO even lighter.

The matte clear coating, in addition to enhancing the carbon texture, protects the end cap from wear and UV rays, keeping the X3 EVO always in a perfect shape.

The sound of X3 EVO is already unmistakable at low revs. X3 EVO has a direct interior, specially conceived to channel the exhaust gas in an optimal way, to unleash a deep sound, giving a new voice to your bike.

The X3 EVO's Spark arrester has been tested and approved by the United States Forest Service and is essential for off-road riding in compliance with regulations, with more peace of mind, more respect for the environment and more fun.
