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

- 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
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.
Optional Heat Shield Strip will protect your airbox from the close proximity of the hot head pipe.
- Select applications available in SX version that is designed for more low to mid-range power and an MX version that is focused in the mid-to-upper rpm range
- Act as "pre-muffler" helping to lower the decibel output
- Available in stainless steel for strength combined with light weight, or in titanium for even greater weight savings
- Utilize FMF's patented module precisely located at the initial stage of the header for specific applications
- Horsepower is increased as much as 10%
- The expansion and contraction of exhaust sonics through the system causes increased flow
- Position "Bomb" increases performance

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

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)
If your aftermarket exhaust is missing heat shield mounting points, 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.
By popular demand. This is our own mid-pipe adapter kit for the GSXR exhaust cans. The unique design works with both 3-bolt Hayabusa and 4-bolt GSXR mufflers. It features all stainless steel TIG welded construction with a laser cut adapter. A spring tensioned slip joint allows for heat expansion. A stainless steel hanger strap allows it to attach to your original muffler mounting point. No welding is required. Mid-pipe length is approximately 17" long.
This mid-pipe does not require a stock muffler joint gasket when used with the stock headpipe, the SS Pro-Flow, or the FMF headpipe, eliminating the hump in flow.
Don't forget a fresh seal ring gasket that fits between your muffler and mid-pipe adapter.
Their baffle was designed to replace the stock insert. The baffle produces a nice note compared to the de-restricted stock version and dyno test results showed an increase on 2 hp up top.
A noise test on the insert was conducted at the EPA Victoria Vehicle Test Station at Macleod under controlled conditions with Class 1 meters.
Tested Bike | ADR Signature dB(A) & test RPM | ADR tess with B&B Tip |
---|---|---|
Suzuki DRZ 400 | 93 dB(A) @ 3375 RPM | 97 dB(A) @ 3375 RPM |
Some extra details:
- The ADR test is conducted at an engine speed which is 50% of the engine rpm at which the engine develops maximum power. However, this engine speed is determined when the bike is in restricted form, with a throttle restrictor that stops the throttle being fully opened. This is why the ADR engine test speeds are so low. However, they are the engine speeds used to determine compliance.
- On the ADR test, the B&B tip was over the signature noise emission, but a tolerance of 5 dB(A) is allowed before prosecution would be initiated. With this tolerance, the insert would not be prosecuted as it is just 4 dB(A) over the signature.
- When tested with the standard OEM tips (as fitted when delivered from Suzuki Australia), the Suzuki came in at 95 dB(A) for the ADR test
Does not contain a spark arrestor. Check local laws on spark arrestors before purchase.
