Hi!!!!
My name is JOSE I´m new in the forum and I´m writting you from Spain. The question is that I have a KAWASAKI KXF 450 2007, and I use it only for SM, I´m going to race the national championship this year. So, I´m going to install an aftermaket exhaust, and I´d like to know which one do you thinks works better in my bike. I´m thinking about the WHITE BROS CARBON PRO, and the AKRAPOVIC. I hope you can help me!!! Congratullations for this fantastic forum!! and excuse me for my english!

What up Jose, I run the Leo vince x-3 ti full system and have no complaints. Plus i am the only person that i have ever seen at the track with this system-i like to be differant. Plus dirt rider and birt bike magazine spoke very highly of it and the workmanship is top notch. I have 40 hrs on it and no problems and the carbon fiber heat shield has saved me more than ounce. I run mine wide open but it comes with a quit tip and a spark arrestor also. I thought that was pretty cool. But the Ak and wb systems are both good to i hear.

I have run the Carbon Pro and the "New" Dr. D on the 07 and found both to provide power increases throughout.

Both great craftsmanship but the Carbon Pro was obnoxiously loud!!! I mean you knew where I was at all times loud.

I really like the Dr. D.
