Great little exhaust.

The exhaust was a direct fit to our 2003 Ttr 90. Installed in about 15 minutes. The only downfall we found was we needed a different jet for where we live. Increased the performance from the exhaust.

Amazing amount of power

Not only does this exhaust system sound nice, it added an amazing amount of power to my son's bike. He has a Yamaha ttr-50 and I wanted to give it a little more power on the hills. Well it accomplished this and more. Added a ton of torque in the low end. He has not gotten stuck on a hill since. Also very easy to install. My 4 year old son practically did it himself, with just a little guidance from me. Highly recommended!

Good pipe.

My sons bike is used for both trail riding and racing, so this is a good pipe for both since it has the spark arrester. Easy to put on and the primary heat shield bolted right up.

A: There is not a specific setting I could give you for jetting your bike. It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend taking your bike to a local motorcycle dealership’s service department to have your bike properly jetted.
Q: How many decibels is this on a TTRL 125?

A: Most aftermarket systems sound pretty much the same. Some have a deep sound and some, after a few miles, have a raspy sound. Some will have a different tone and even the same exhaust system can sound differently on different models of motorcycles. In general most systems are around 92 to 98db's.
If you run your rpm up to the rev limiter the db's may go as high as 100 to 102+db's.
Q: How many DBs is this exhaust I want LOUD! vs the spark arrestor version?

If they are the same can I get the spark arrestor version and take the spark arrestor out if I wanted it louder

A: The version of the FMF Powercore 4 without the Spark Arrestor will be slightly louder than the version with the Spark Arrestor. The Spark Arrestor in this exhaust is not removable.

What do you need on your bike to install this
MotoSport Staff Expert
Over 3 years ago Location: Portland, OR, USA
A: You may have to do a small amount of tuning to the jetting when going to this exhaust on your Yamaha TTR125L. A high performance air filter isn't completely necessary but would be a great idea to increase the performance on your bike.
