Exhaust

The headpipe gasket seals the joint between the head pipe and Exhaust port. These gaskets are designed to crush a little bit to tightly seal where the pipe fits to the head, thereby making them a single use part. Get a fresh one now avoid having an exhaust leak when you install your new exhaust.

The muffler joint gasket seals the joint between the head pipe and muffler. These gaskets are easily damaged when removing the original muffler. FMF mufflers (Q4 or PowerCore 4) do not require a joint gasket but the all other aftermarket mufflers as well as the stock muffler do require a joint gasket. Get a fresh one now to ease installation of your new performance muffler.

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.

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
