Sounds great

Bought this a few weeks back already notice a huge difference in power and response. Along with the bike being quieter it sounds great. Also like the fact that the header doesn’t stick out a mile like other brands.

Love it

Very easy to install and it makes the 450 sound like a 450 it’s supposed to

Q: Can i fit this in my bike?
Over 5 years ago
So i was wondering if i can make my Yz-85 04 a dual exaust bike. I dont mean with this product but i really want it to be dual and i only need the conector from the pipe to the exaust. Can i buy it alone? And now i have a FMF powercore 2 shorty, will i need the same silencer? I know my question sounds crazy but just asking.

A: To my knowledge there is no dual exhaust system or dual connecting pipe that would be made for your Yamaha YZ85. The Dual Mid-Pipe or "Y-Pipe" for this FMF Exhaust would be far to large in diameter to adapt to your bike. It would likely be something you would have to have custom fabricated.
Q: Is there an advantage to having the dual or is the single exaust made by fmf create just as much power

A: I contacted FMF directly for you and this is what they said:

"The dual parts are great on performance but the single exhaust are almost always better on performance. On this and past systems it is true that the single will produce better performance all around over the duals. The duals will be a little quieter due to the exhaust being split into two mufflers but the single will still meet sound for AMA." -Bryce, FMF Racing
