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.

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!
The product has lived up to it's description. Very happy with it and the delivery came before expected.
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.
I ordered the fmf power core 4 for my 02 yamaha ttr125l and fit great and sounds awesome. Definitely recommend motorsport.com to everyone there customer service is hands down helped me with all questions before I ordered thanks a lot
Got this for my kx 250f fit great, sounds great
If you run your rpm up to the rev limiter the db's may go as high as 100 to 102+db's.
