Description

Your rear end? The only dyno that matters.

You bolted on a cold air intake. You added the wing from a 747. You installed the magnetic fuel vortex harmonizer and triple-ionized muffler bearings. Any of our quality performance products. You felt it. You know it added power. But your friends, blinded by dyno charts and facts, just won’t believe you. 

That’s where the KaleCoAuto Butt Dyno comes in.

This precision-calibrated racing seat features:

  • Dual chrome rollers positioned exactly where your glutes can feel the gains
  • Integrated horsepower and torque curve display
  • Embroidered KaleCoAuto branding for street cred
  • Chipotle rated

Pairs perfectly with your existing mods, including:
Cold air intakes, sonic fuel line enhancers, racing stickers, 9″ fart cannons, whistle tips, and electronic turbos.

Installation is simple: Mount the seat, mash the gas, and do your thing. No need for wires, additional computers, or reality. Just your instincts, your mods, and your trusty cheeks.

Disclaimer: Won’t win you races. Do not sit on the seat without pants. Has no affect on passengers. May significantly reduce gas mileage. Cannot be installed in same position as Passenger Ejection Seat.

    Chazzzzz – July 3, 2025

    Bro, I slapped this in my Civic and instantly felt like I picked up at least 30 extra horses. Zero proof, but my butt says we’re ripping now. Feels just like family you know, Fast and Furious style even if I’m still getting smoked by minivans. Cheah. My AC was on.
