Learn how to install the Yoshimura AT2 stainless slip-on exhaust on your Suzuki GSX-S750, with step-by-step instructions, common mistakes, and fitment tips.

Quick Answer

The Yoshimura AT2 stainless slip-on exhaust is a direct-fit upgrade for the Suzuki GSX-S750/Z (2018-2023), and with the right tools and careful attention to alignment, you can install it in about an hour.

Why the AT2 Stands Out for the GSX-S750

The AT2 slip-on is a cousin of the Alpha Taper muffler, but it brings its own styling with a matte carbon fiber end cap and heel guard, plus a faceted inner end cap in Yoshimura's Works Finish. For GSX-S750 owners, it's a straightforward way to shed weight and sharpen the bike's look without replacing the entire system.

Because this is a slip-on, you keep the stock header and catalytic converter. That means installation is simpler than a full system, but it also means you won't see the same peak gains as a full exhaust. If you're after maximum performance, a full system is worth considering; for most street riders, the AT2 delivers the sound and weight savings you want.

What You Need Before You Start

Gather the tools: a socket set with extensions, a torque wrench, penetrating oil, and a clean rag. You'll also need the mounting hardware that comes with the kit—don't reuse old bolts if new ones are supplied.

Work on a cool engine to avoid burns and to make gasket removal easier. If the bike has been ridden recently, let it cool completely.

Step-by-Step Installation

Prep the bike: Place the motorcycle on a stable stand and let the engine cool completely. Remove any saddlebags or bodywork that might block access to the exhaust mounting points. Check that the stand is secure before you start.
Remove the stock muffler: Loosen the clamp at the mid-pipe connection and the mounting bolts at the passenger peg and rear bracket. Support the muffler as you slide it off—don't let it hang. If the stock muffler is stuck, apply penetrating oil to the joint and let it soak for a few minutes.
Clean the mid-pipe: Wipe the mid-pipe surface with a clean rag to remove any carbon buildup or debris. This ensures a proper seal and prevents exhaust leaks. Inspect the gasket; replace it if it's worn or damaged.
Mount the AT2 slip-on: Slide the AT2 slip-on onto the mid-pipe, aligning the mounting brackets with the existing holes. Hand-tighten the clamp and bolts to hold it in place. Don't fully tighten yet—you'll adjust alignment next.
Align and torque: Adjust the muffler so it sits level and has even clearance from the swingarm and rear tire. Tighten the clamp and mounting bolts to the torque specs in the instruction manual. Check clearance by spinning the wheel and compressing the suspension.
Final check: Start the engine and listen for exhaust leaks at the joints. Let the bike idle for a few minutes, then re-check the bolts for tightness after the first heat cycle. Re-torque after the first ride—bolts can loosen as the gasket settles.
