Straight answers on GSX-8S and GSX-8R Race AT2 full exhaust fitment, track setup, and installation questions, based on the 776cc parallel-twin platform.
Quick answer
The Yoshimura Race AT2 Stainless Full Exhaust is a track-focused system for the 2023–2026 Suzuki GSX-8S, GSX-8R, GSX-8T, and GSX-8TT. If you are setting up a dedicated track bike, start with the product page to confirm your exact model year and then follow the installation checks below.
Why the 776cc parallel-twin changes your setup approach
The GSX-8 platform uses a 776cc parallel twin with a 270-degree crank, which gives it a distinct power character and sound compared with older twins. The Race AT2 full system was developed specifically to optimize that engine, so the gains are most noticeable when the bike is tuned and ridden in the upper rev range. On the street, you may notice the weight savings and sound more than a dramatic power increase, which is why this system is positioned for racers headed to the track.
What the Race label means for daily use
A Race Series exhaust is intended for closed-course competition and may not be legal for street use in your area. The AT2 full system replaces the entire exhaust from the header back, so it is not a simple slip-on swap. If you need to keep the bike street-legal or quiet enough for local noise limits, check your regulations before ordering. The stainless muffler and works finish are built for track conditions, not for long-term cosmetic durability against road grime.
Fitment across GSX-8S, GSX-8R, GSX-8T, and GSX-8TT
The product record lists coverage for the 2023–2026 GSX-8S, GSX-8R, GSX-8T, and GSX-8TT. That range covers several model variants, but it does not guarantee that every sub-model or market version uses identical mounting points. Before you start, confirm your exact model year and variant against the product page. If your bike is outside the listed years or has non-standard bodywork, test-fit the system before fully tightening anything.
Track setup and installation questions
- Will this exhaust fit my 2024 GSX-8R?
- The product record lists fitment for the 2023–2026 GSX-8S, GSX-8R, GSX-8T, and GSX-8TT. Check the product page for your exact model year and variant before ordering, because market-specific parts can vary. Verify your model year and variant on the product page before you buy.
- Do I need a fuel controller or ECU flash?
- A full exhaust system changes airflow enough that the stock fuel mapping may not be optimal. For track use, many racers pair a full system with a fuel controller or ECU flash. The product record does not specify a required tuning device, so consult a qualified tuner for your setup. Plan for tuning if you want the most from the system on track.
- What should I check during installation?
- Test-fit all pipes and the muffler before final tightening. Check clearance around the swingarm, footpegs, and bodywork, and confirm the carbon fiber heel guard is positioned away from your boot. Use new gaskets where required and tighten fasteners in the sequence recommended by the service manual. Do a full dry fit and clearance check before torquing anything.
- Will it pass track noise limits?
- Track noise limits vary widely by venue and event. The product record does not list a decibel rating, so you cannot assume it will pass a specific limit. Check with your track or sanctioning body before you enter, and consider a sound insert if rules allow. Confirm the noise limit with your track before race day.
- Does the Race AT2 system include everything I need?
- The product record describes a full system with a stainless muffler and carbon fiber heel guard. It does not list gaskets, hardware, or a tuning device as included. Review the product page contents and order any consumables your service manual requires. Check the box contents against your manual before starting the job.
