Description
The Honda CB750 Hornet is here and Yoshimura has the insane sound and look of the AT2 Street Series slip-on ready to go!
As soon as we heard the CB750 Hornet was coming to the USA we got excited! We're big fans of the 755cc parallel twin engine and in the chassis of the CB Hornet, this bike is a blast to ride.
Giving the 750 hornet more performance is what we are here for and our AT2 makes it happen.
Our slip-on helps the New Hornet loose a substantial amount of weight. 3.4 lbs. to be exact. In the performance numbers the AT2 can provide up to 1.5% more HP at 8,500 rpm and up to 2% more torque at 7,500 rpm. doesn't stop there. The exhaust note that the AT2 produces makes is second to none! The AT2 also comes with a custom carbon fiber heal guard.
Yoshimura's AT2 is designed, developed and manufactured in Chino California.

Preordered this slip on in July. Was excited cause there was not a lot of options for parts since this bike is so new to the USA. Arrived very shortly after I was informed they started production. Shipping was very fast. When the pipe arrived couldn’t wait to install. Installation was very easy. I had heard other videos of this exhaust so thought I had an idea of the way it would sound but it was far better in person then I expected. Has a great throaty tone. Is way lighter than the oem and drastically better looking. Yoshimura makes the best exhausts in my opinion high quality and great sound. Would recommend!
I absolutely love the sound this thing makes. It looks great on the bike and was worth every penny. Love it!
Amazing! Continues to be the best in the Business! AT-2 exhaust sounds unreal and looks incredible too!
This review is for the Yoshimura AT2 Slip-on the 2025 Honda CB750 Hornet. I wanted to update, open up and lighten my 2025 CB750 Hornet with a nice after market slip-on, Yoshimura became my candidate of choice with my previous positive experiences with their products and excellent customer service (including rebuilding damaged exhausts). The AT2 slip-on is a top tier unit that sweats the details. The unit exudes quality with first rate materials, precision formed parts, solid construction, and pristine quality finishes. Notable features like a Heliarc welded exhaust flange (instead of a cheaper, generic strap hanger), Stainless Steel body/Carbon end cap construction, tunable sound insert options and parts/support for rebuild makes for a solid resume. Ordering directly from Yoshimura, the slip-on came in a secure box, wonderfully wrapped/protected; The installation was easy, everything aligned and it went smoothly (I used an aftermarket solo hanger). BTW I installed the INS-27-K sound insert on my unit. And if you opt for the sound insert, I suggest you install it prior to mounting on bike for better access and alignment of the tricky, tiny set screw and star washer; you've been advised. The slip-on looks and sound great! Even with the sound insert, it is still plenty loud but more "reasonable". The parallel twin hoots and snarls in a healthy, strong, deep tone. Engine pull is strong and linear with an audio crescendo, And you save 3 1/2 lbs.to boot, what is there not to love? Making mods is fun and this one is pretty cool. I like supporting a good company like Yoshimura, they have a long history and a well deserved track record (I bought my first Yoshi exhaust in 1983). As the title says, the AT2 puts the sting in this Hornet!
Thanks David, you nailed it!
Looks great, sounds great, easy to install. Great job yoshi!
