The Best of Both Worlds

The StreetMeg™ combines our Generation 3 front section and sidewinder megaphone muffler to provide race-proven performance with a classic drag race look. Eliminating the inherent drawbacks of a side exit system, there is no reduced right hand cornering clearance, or rear brake lever-to-pipe clearance issues. No fairing modifications are required, and the stock oil cooler and lines remain intact. From carving corners, to wide open on the salt flats, the drag-inspired look and deep throaty sound of the StreetMeg™ says, “Let’s RACE!”

    Streetmeg Full System Black Carakote, Power Programer, Silencer

    Posted by Joel on Sep 30th 2019

    Installed on a 2019 Kawi Z900 RS CAFE with 1000 miles. Seemed expensive overall but try to piece together other systems and you will exceed the cost of Brock's. Also purchased with the power programmer preset with the street performance map. Sound is loud and awesome causing me to not want to put in the silencer right away. Silencer does tone it to neighborhood friendly levels with low throttle. Performance... Wow . No regrets . There was a notable difference in the pull of the bike throughout its entire range. Don't hesitate to get this system for your RS 900. I did the install myself which wasn't to bad just be sure to cover the pipes with painters tape to protect the finish during install.

    Streetmeg Full System Black Cerakote

    Posted by Troy Black on Feb 6th 2019

    I was looking for a full system that could be tuned to match the Z900RS. I watched quietly as Brock developed parts for this bike and shared them with us via youtube vids. After corresponding with another customer who had already bit the bullet, I signed on for the full Stock to Brock package. This exhaust looks great on my RS Cafe'. The throaty roar is addictive but admittedly loud for street use. I also purchased the noise suppressor insert but have yet to try it. It just sounds SO GOOD as it is. With the PAIR blocked and O2 sensor removed as instructed, there is no popping on decel. Working in conjunction with the ECU flash w/mapping, the exhaust runs fantastic, looks fantastic, and sounds mean!

    Awesome look and sound!

    Posted by Scott Beauchene on Aug 30th 2018

    Like many the Kawai Z900RS harkens back to the days of he Z1, KZs and GPZs that I pined for as a teenager. I remember the looks and sounds of those bikes with the old Kerker 4-into-1 exhausts everyone installed back then and so when I n search of a comparable exhaust and found the Streetmeg to be very close. The looks are old school and match the bike very well. The sound is incredible and is very similar to what he Kerkers sounded like. The exhaust is loud, I know it's for track use, but if the outlet was smaller or if it came with a removal baffle it would be perfect for the street. Yes you can get a suppressor and I did and it works well, but for an exhaust that costs this much it should have come with it. The only reason I did not give it five stars is because the cost is a bit high, especially for not including the suppressor.
