Graves Motorsports 2017-2018 Kawasaki ZX125 Full Exhaust System with Carbon Fiber silencer. GMS Exhaust systems are designed for the elite rider seeking top of the line performance, fit, finish and value. This Z125 exhaust system was developed using the same technology that has powered Monster Energy Graves Yamaha riders to 7 straight consecutive Moto America / AMA Superbike championships along with numerous 600cc titles. This product is intended for closed course competition use only. Use of this product for any other purpose is strictly prohibited.
We did not allow compromises in the development of this system. Material diameters, lengths, the silencer core size and length are optimized for maximum power output throughout the throttle and RPM range.
We use high heat grade Titanium tubing. This material is designed special for maximum durability and oxidation resistance up to 800*Celsius / 1472*Fahrenheit. It is designed to live at almost twice the temperature of normal Grade 2 Titanium. The tubes are precision bent and cut with the latest equipment available. The tubing is then welded in fixtures designed so that repeat-ability is second to none. It comes with a single Lambda receiver bung for on track data logging or Dyno tuning. The spring tabs are made from 4MM thick Titanium wire for long life.
The silencer mounts to the motorcycle using a built in strapless aluminum mounting bracket for the cleanest look possible. The silencer body attaches to the end caps with stainless aircraft grade rivets and Titanium silencer bands. The inter core tube is made of stainless that slips over the entrance and into the exit cap that is made of Titanium and accented with a Carbon Fiber beauty cover with a 60* slash cut.
This system performs like our superbike pipe and shows like jewelry.

2Brothers has yet to let me down. Great Slip on set up, deepens the sound without making it obnoxious. Easy install, took about an hour with wrapping the mid pipe. I recommend wrapping the mid, it is much hotter than stock without the wrap. Thanks Bill! -Jon
Not difficult to install. Most likely will require to replace the muffler gasket. Matches well the look of the bike. Sounds well at low to mid range, a little noisy at high RPM.
Exactly as described. Once again, Bill and team have provided a quality, well priced item. They are quick to contact with any possible wrong fit, possible issues, and always have been spot on with solutions or suggestions. Will use Bill's Performance for all my motorcycle needs. Highly recommend this company. (2010 HD Heritage Softail Classic)
I want to highly recommend Bill's Performance for all of your part needs. The entire experience was great. I was having an issue with the FP4 not connecting to my bike. I contacted Bill directly on the phone on Saturday and we were able to resolve the issue with no problems. His response time, patience with me, and customer service are top notch. I will purchase from him again. 10/10 rating. You will not be disappointed. Thank you Bill!!
This is my second exhaust from bill in 6 months for two different bikes he had exceptional customer service and always staying on top of time frame and his prices are better then anyone out there . Overall what makes Bill stand above the rest is his customer service and his passion for bikes that itself tells you what kind of person he is and his enthusiasm for motorcycles.
Bill’s exhaust personally took the time to customize my experience and be sure I got exactly what I was looking for at the best possible price. There was quick & attentive communication for all my needs and I am extremely pleased with my product and service recieved.
Had some fuelling issues in the midrange - tough to find ECUs for bikes of this age these days. Power commander sorted it out, very happy with my purchase and Bill's service.
Bill is a solid guy - will definitely shop here in the future
Had a bit of a miscommunication with the shipping timelines offered on the website as the part had to leave the vendor, arrive at Bill's shop and then be shipped to me. I reached out to Bill and he was quick to do what he could to make it right. My part arrived as quickly as he could make it happen and I appreciated the effort he put in. I'll definitely be shopping here again, fair prices and a good guy to work with.
Amazing product and phenomenal change is performance . I really loved it
Thanks to Bills performance for the amazing service and quick shipping
Highly recommended service
