Hi guys,

I am struggling to choose the right performance exhaust system for my KX450F.
The bike is 2015 and is completely stock. I am not going to modify the bike, but I would like to add some bottom end torque.

Can anyone suggest something special for my bike, it would be super nice if you have had something on you stock Kawa also.

Right now I am on FMF Factory 4.1 side.

I have looked over the internet, but not much unbiased information. Found this review here , looks kind a good.
Snowflake, I have thought about Dr. D, but also heard some bad stuff, that it is not that good for Kawasaki. Maybe I am wrong. What are the main things to know about Dr. D?

I have a Dr.D on my bike (09) other than the black finish on the end cap wearing off it is a very well made unit that offers a tad better bottom-mid.

Remap the ignition and fuel. It's a 450 and unless you are riding super tight SX at a pro level then no mods are needed other than suspension. Save your money for gas tires and oil.
