Straight answers on fitment, track prep, and what the Hayabusa 2022-26 Race AT2 Stainless Full Exhaust actually changes before you commit.
Quick answer
Treat the Hayabusa 2022-26 Race AT2 Stainless Full Exhaust as a track-focused system: confirm your bike is a 2022 or newer Hayabusa, plan for a full exhaust install rather than a slip-on, and verify your track's sound limits before you commit.
What the Race label means for your Hayabusa
Race Series exhausts are built for closed-course use, so the AT2 full system is not the same purchase decision as a street slip-on. That matters most if you split time between track days and public roads: check your local regulations and the rules of the organizations you ride with before assuming this system is street-legal in your area.
The catalog also does not list a dB rating for this system, so sound compliance has to be confirmed with the track or sanctioning body directly rather than guessed from the product page.
Full system versus slip-on: what changes on the 2022-26 Hayabusa
A full exhaust replaces the entire system from the header back, while a slip-on keeps the stock header and mid-pipe. On a newer Hayabusa, that difference affects installation time, how much of the stock hardware comes off, and how the bike is tuned afterward. If you only want a different look and sound with minimal downtime, a full Race system is more work than you need.
Because no tuning or fuel-management specifications are supplied for this system, treat ECU or fuel tuning as a decision to confirm with a qualified tuner rather than a step you can assume from the product listing.
Where the weight savings actually show up
Yoshimura states that weight was removed compared with the stock system on the new Busa, but the catalog does not publish a specific weight figure. That means you should treat weight loss as a real design goal of the AT2 rather than a number you can quote. The practical effect on track is felt in direction changes and braking, not just on a spec sheet.
Hayabusa Race AT2 track setup questions
- Will the AT2 full exhaust fit my Hayabusa?
- The catalog lists this system for the 2022-26 Suzuki Hayabusa. If your bike is an earlier generation, this is not the correct fitment and you should look for a system listed for your model year. Confirm your model year before ordering; 2022 and newer only.
- Can I install it at home before a track day?
- This is a full exhaust, so it replaces the header and mid-pipe, not just the muffler. Plan for more than a simple bolt-on job and allow time for a shakedown ride or dyno check before the event rather than installing the night before. Book installation and a check ride well ahead of your track date.
- Do I need a tune after fitting the full system?
- The product listing does not specify tuning requirements, so treat this as a question for a qualified tuner who knows the 2022-26 Hayabusa. Do not assume the stock calibration is correct for a full Race system. Get tuning advice before you ride the bike in anger.
- Will it pass my track's sound limits?
- No decibel figure is supplied in the catalog for this system. Check the sound limits of the track or organization you ride with and confirm before you buy, since Race Series systems are intended for closed-course use. Sound compliance is your responsibility to verify, not the listing's.
- What finish and materials am I getting?
- The system uses a stainless muffler with a matte carbon fiber end cap and heel guard. That combination is what you will see and maintain on the bike, so decide whether the carbon trim matches the look you want before ordering.
