Sounds amazing.

This pipe woke up my 2019 yz125. Night and day difference compared to stock. Be sure to oil the pipe with WD40 when in storage. Works finish looks amazing

Great power

Bill's pipe is the only way to go with a Zook 2 stroke! I tried 3 different pipes on the 125 and this is by far the best.

Quality Could Be Better

I bought a Bill's works pipe and silencer to replace my 4 year old Pro Circuit system, but the quality of the pipe I received wasn't that great. The pipe already had surface rust on it and one of the mounts didn't have the nut welded on it so I had to add a nut in order to install the pipe. If extra hardware is required for installation then it should be included. I sent a message to Bill's Pipes to ask them about it but never received a reply. It is still nasty in KY so I haven't had a chance to ride the bike yet, hopefully the performance will make up for the installation issues. If I had it to do over again I would have just bought another PC works pipe and R304 silencer.

A: It can be used with Bill's Pipes silencer or stock silencer. Providing the Pro Circuit is the same diameter as stock, yes.

A: It's likely that your 2019 YZ250X may not require rejetting after installing the Bill's Pipes MX2 Works Pipe.

Whether for a sport bike, dirt bike, cruiser, or ATV, an after-market exhaust system or a slip-on muffler will improve the performance of your motorcycle, which is particularly important for the race track and competition.
The stock exhaust systems are designed to meet the emissions and noise-level restrictions set in place by most federal, state, and local authorities, and laws vary from state to state. It’s important that everyone check with local laws to understand what changes to your stock exhaust system are permitted.
Most after-market exhaust parts are lighter weight than the originals from the manufacturers. Most after-market exhaust parts allow the exhaust to flow more freely, and with reduced back pressure, and thereby improve performance. Performance improvements might be achieved with higher horse power and top end speed, or tuned for better low-end torque and quicker acceleration.
Allowing the exhaust to flow with less restriction usually demands adjusting and retuning of the fuel/air system, whether it is carbureted or fuel injected. In many cases, you might not know whether or not adjustment or retuning is needed until after you installed the new exhaust and taken it out for test-ride.
Some carburetors allow you to adjust the fuel/air ratio and the idle, but in some cases, changing the exhaust might require rejetting. Check out the simple guide to rejetting your carburetors: http://www.motosport.com/blog/a-simple-guide-to-jetting-your-carb
Fuel injection systems are usually electronically controlled. Adjusting and tuning fuel injection systems usually require a fuel management system. http://www.motosport.com/blog/sportbike-and-motorcycle-fuel-management-guide
