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.

Some extra details:

1. 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.
2. 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.
3. 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

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)
