i have them

Hi, we have 2 yfz450r built mx bikes with barkers and we are very impress. They make great power everywhere and sound, quality and fitment is 1st class, i would highly recommend them over anything out there, and KB Motorsports is the way to go hes got the best prices on that exhaust.

We have been selling alot of Barker systems lately.... they seem to be one of the top of the line systems. i know that i have had a bunch of happy customers!

 

I have dynoed the Barker and Dasa on my R. The Barker makes .25-.50 hp more throughout the rpm range, comes on sooner, and lasts longer on the top end.
My mods are: 13.75 CP piston, port, MSD ignition, gutted airbox, K&N filter, and Barker exhaust. Just had this done last week and I'm happy to be running the Barker

Buddah whats the DB on that pipe? Insanely loud or does it meet sound requirements for public riding areas?

 

I've been running a Barker for a while on my YFZ450R. Power gains are awesome and the fitment and quality is even better! I'd highly recommend Barker exhaust!

These look pretty neat, I was set on a Dasa..... never heard of the this company though. I hate it when you think you have your mind made up lol. Fit and finish look very nice. Sorry to jack the post... but how big is the exhaust tip on the barker?

 

Tim Barker has been well known for somtime. He builds awesome performing dual pipes for the 700 Raptors, which I run as well.
