Product details
Yoshimura ZX-4RR 23-25 AT2 Stainless Slip-On Exhaust, W/ Stainless Muffler
The new Kawasaki ZX-4RR sport bike is one special machine. Engineers at Kawasaki set out to develop a 400cc inline four cylinder engine built for high performance, and they delivered.
For this special machine we used our AT2 muffler to develop a Street Series Works Finish slip-on giving power to the 16,000 + RPM's of the new Kawasaki powerplant. The AT2 came through in performance, sound, and weight savings. HP was bumped up by an increase of 3% and torque was bumped up as well, adding 4.3%. Our mission of adding power and torque throughout the entire spectrum was accomplished. Our AT2 Slip-on removed 4.5 pounds from the stock formation.
The sound of this inline four at 16,000 rpms with our AT2 is simply something that must be experienced in real life. True music! Finally, the styling of the AT2 can't be beat. It's now iconic matte carbon fiber end cap and heat shield compliment the lines of the ZX-4RR to perfection.
Our AT2 slip-on is proudly designed and manufactured in Chino, California.
This product was designed to fit on a standard equipped motorcycle, as delivered from the factory. OE and aftermarket accessories not found on a bike as delivered from the factory may not be compatible with this product.
Attention international customers: This product was designed and tested to be compatible with vehicles in the U.S. marketplace only. Compatibility, including fitment and performance, may vary by marketplace.
