The ultimate full exhaust for the SUZUKI Hayabusa will be available soon! The best build quality in YOSHIMURA history!
This prototype full exhaust for the SUZUKI Hayabusa, which was announced as coming soon at the March Motorcycle Show, was on display in May. It was revealed that this exhaust has been built even better than any YOSHIMURA exhaust released in the past, so Hayabusa owners should definitely check it out!
The champion of YOSHIMURA exhausts
The demo bike on display was equipped with the dual titanium full exhaust system that had been shown for the first time at the motorcycle show.
Shaped like the R-11Sq R
The basic shape of the silencer is the same as that of the "Slip-on R-11Sq R Dual Cyclone" exhaust, which went on sale May 10. The slip-on has a choice of silencer cover finishes: SSF (Satin Finish Cover), SM (Metal Magic Cover), and STB (Titanium Blue Cover), which will probably be available for the full exhaust as well. The silencer cover on the demo bike was the STB (Titanium Blue Cover), which weighs the least of the three.
The silencers are similar but not quite the same
There are distinct differences between the slip-on and full exhaust. The biggest visible difference is the mesh at the silencer end. This mesh on the exhaust port is familiar as being used in recent years in motoGP and the EWC (Endurance World Championships). Although YOSHIMURA is known for competing in the Suzuka 8 Hours Endurance Road Race, this is just one of the EWC races held throughout the year. In fact, YOSHIMURA has been participating fully in the EWC since 2021, and feedback from their race experience has been poured into this new product. This mesh was originally designed to prevent gravel from getting into the engine and causing damage in the case of a crash or going off the course during a race. And so it may seem purely visual when used on public roads, but there is no way that YOSHIMURA would equip their top quality exhausts with a meaningless feature. In fact, it was found that the mesh increases the exhaust pressure and has a positive effect on power output characteristics.
Different silencer cover materials
Even though the silencers on the full exhaust and the slip-on have the same shape, they use different materials. The most easily distinguishable part is the portion of the cover just before the silencer. For the slip-on silencer, it is made of stainless steel and has a beautiful polished surface. For the full exhaust, on the other hand, it is made of titanium. The surface finish is also different, with a satin finish instead of a polished finish. This change gives off a very different look when installed. The feel is similar to that of YOSHIMURA racers competing in the EWC.
Differences that cannot be seen
Although it is not obvious from the outside, there is actually a difference inside the silencer as well. In the case of the slip-on exhaust, stainless steel is used for the noise reduction perforated pipe inside the silencer, but in the case of the full exhaust, all the internal parts are made of titanium, so the perforated pipe is titanium too! It is very rare to have an exhaust made entirely of titanium, including the perforated pipe, and this alone makes this full exhaust worth it. Though perforated titanium pipes are known to have short life spans in exchange for their light weight, YOSHIMURA quality ensures that it will not break, as proven by their EWC race results.
Nothing but YOSHIMURA's finest
Of course YOSHIMURA has pulled out all the stops preparing their highest quality exhaust for SUZUKI's flagship Hayabusa. This full exhaust for the Hayabusa is the end result of a pursuit of performance in a different line from their usual hand-bending. The welds are beautiful as always, but another key point is the installation of two small sized catalytic converters, which are placed in inconspicuous positions to take advantage of the twin-pipe design. Since the catalytic converter area is doubled, exhaust efficiency is not compromised in the name of air purification performance. The silencer capacity is also doubled, which contributes to noise reduction. The carbon heat guards appear to be the same as the slip-on, but what is noteworthy is how they are secured. While most heat guards have screws visible from the outside, these heat guards only show carbon and nothing else. It's a small detail, but adopting a time-consuming method for the sake of quality proves that this product is top of the line.
Orders for the slip-on type started on May 10th
The slip-on type with a silencer of almost the same shape is already on the market. The suggested retail price for the slip-on is 277,200~ JPY (including tax). The silencer in the image is the STB (Titanium Blue Cover) with a suggested retail price of 305,800 JPY (including tax). As noted above, the basic shape of the silencer is the same as the one used for the full exhaust, with the difference being that there is no mesh at the silencer end and the cover is polished stainless steel. There is a clear difference in appearance when the silencer is installed, even though they have the same shape. The full exhaust has a unique atmosphere that can be described as "powerful" or "stunning". However, the price of a full exhaust is sure to exceed that of a slip-on, which will be a dilemma for owners.
Anticipated Specifications
The following specs are known at this time:
■Compatible bike model: HAYABUSA (21-23)
■Compatible model number: 8BL-EJ11A
■Compatible engine model: DXA1
■Material: Full titanium
Release date: Around summer of 2023
Close proximity and acceleration noise volume, as well as weight are unknown at this time, but the weight should be astonishingly light, benefiting from the full titanium specification, despite the disadvantage of having two pipes. It is certain that it will have the high quality expected from YOSHIMURA, a high degree of sturdiness that will not take damage from a minor fall, and the durability to last. It will definitely leave its mark in YOSHIMURA history as the ultimate exhaust made of the best materials, with the best performance, and the longest life. The expected name of the product is "Titanium Machine Bent R-11Sq R Dual Cyclone".
