Awesome Headpipe, no problems, just got back from some HARD riding at the dunes and pipe held up awesome, Fit onto 06 yfz 450 with stock slip on perfectly, now Im waiting on the DR.D slip on the be in stock so i can buy that to complete my system... Great low end grunt with just the stock slip on compared to the stock head pipe.

***2006 YFZ450*** Works well with stock slip on. I enjoyed the thick flange. No issues with the flange deforming. Added a little bit of low end grunt and a nice tone overall.
great head pipe fits amazing with the muffler!! super stoked to ride with this.
I Installed this Head-pipe to the slip-on Exhaust from Dr.D I had purchased months ago! This head pipe fits well and the power was amazing over the slip on!! Much more power on the low and mid range, and it almost completely elinimated one of the biggest problems the YFZ has...Low end Throttle Bobble! My YFZ powers out of corners like never before...in Higher gears with no clutch work involved! I have not encountered any throttle bobble since the install one month ago also! Big PROPS to Dubach Racing! They have made a wonderful Product!
