My son is stoked that he has his fmf pipe just like dad. Happy with the purchase!
My kids have Honda CRF110F wanted to sound like dad’s bike. The swap was effortless and the stock heat shroud bolted right up to the new pipe. It’s a good buy.
Bought a month ago for my son and his words are above..
My son purchased this for his dirt bike. It was easy to install & he loves it!
Works great, fits great. Just sticks out a few inches past grab bar. Really need extended grab bar to protect head from cracking.
I love FMF and have it on all my bikes so figured I’d add it to the pitter and it’s awesome. Added about 5mph to the previous top speed and sounds so much better, but it is loud.
Installed on grandson's Honda he rides in Air Cooled class, for hillclimb said. Work great really woke that bike up.
Bought this for my kids 18 crf125. Noticeable power gains and quick easy install.
Honda does not list a TRX300X for 2003 in the US.
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
