    Great test @Moore Mafia! Please don&apos;t forget that our oversize tubing diameters are specifically designed to work in conjunction with the bikes ram air functioning at high speeds, for an even bigger performance boost while moving, that the dyno can&apos;t read. We have experimented with all sizes, the smaller tubes do help low end power, especially at partial throttle openings.... but here at Brock&apos;s, we don&apos;t race at partial throttle and neither does the other lane😜 <a href="https://www.youtube.com/hashtag/stupidfast">#stupidfast</a>

    M4 sounds a smidge more aggressive, and performs better for the street. Brock&apos;s looks better and performs better for the track.

    Both companies make great products, don’t sleep on the bricks as he’s a very experienced racer with lots of knowledge and wisdom. Depending on your goals can’t go wrong with either one.

    I run the M4 on my S1K. Dude Mungus runs the M4 exhaust on his GXSR 1000 and his bike be killing it. Has topped out at 203 mph on GPS.

    Im so ready to see what can be done on the 2026 GSXR 1k ...... with the compression changes and a few other things they did with the motor I believe mooremafia will be able to get some serious HP out of it

    As someone else said both companies are excellent. I’d argue one has experience at a road course the other at the drag strip. It all comes down to your own personal goals and the type of riding you do.
