Yeah, we know the pipe makes the powerband on these, ofc. You may get lucky adapting a 1-size-fits-all pipe to your engine, but part of the reason customizeable kits like the pipe SBP sells is that you can tune it for your drivetrain's setup and desired speed. You seem to be tuned more for low-midrange torque than max HP atm. That sounds good to me, but I'm I know you got a mean lil race-capable engine there. Fred knows his biz. So you have to tune your exhaust for better high-RPM driveability. Seems like some others in this thread already have experience with the pipe you're using, so you should def hear them out. You may find that you already have too-small of a sprocket once you're set up proper. I ran a 34T on mine mainly just to keep revs down at 20-30MPH cruise.
