GSX8 M4 testing

The below video gives a detailed breakdown of my results with testing and tuning the M4 full scalene exhaust on my GSX8. Individual dyno runs posted below if you do not want to watch a video. My flash and the exhaust is available for sale at the bottom of the page

I weighed the M4 system at 10.6 lbs for a 6.4 lb savings from stock. As it comes it measured 80 db at idle and pegged my meter over 130 db on the run. With the DB killer installed it measure 70 db at idle and 110 db on the run. The bike actually performed better with the DB killer installed

The first dyno run shows the stock bike(blue) vs the M4 exhaust, stage 1 AB mod, and my flash (red)

This dyno run shows the stock bike(blue) vs the M4 exhaust, stage 2 AB mod, and my flash (red)

This dyno run shows the exhaust with the stage 1 ab mod db killer in(red) vs db killer out ( blue)

The below run shows the DB killer in(red) vs out (blue) with the stage 2 air box mod, not a clear winner this time.

GSX8 V-Strom 800 sprint filter

$95.98 - $249.00

EFFICIENCY & FILTRATION

The Sprint Filter polyester air filters retain

93.13% of 100 μ particles (Sprint Filter P08 air filter)

91.8% of 37 μ particles (Sprint Filter P037 air filter)

95.22% of 100 μ particles (Sprint Filter P08F1-85 air filter)

versus the 76.42% of 4-layer oil-soaked cotton

ESSENTIALLY MAINTENANCE FREE

Sprint Filter air filters cleaning procedure is straightforward and quick: use an air jet, in the opposite direction of suction, to remove most of the debris collected. No washing or drying is necessary, so the filter can be refitted immediately. Maintenance of the air filter is essential for the protection, care, and efficiency of the engine. A clean and undamaged filter will always ensure the correct quantity of clean air for the air box. Another air filter maintenance aspect is how long it takes to clean. Apart from the time required for disassembly and reassembly, cotton and sponge air filters demand downtime for washing, drying and oiling the filtering element, none of these operations are required with a Sprint Filter air filter.
