slip on for yfz450 which do u guys prefer, or another pipe thats not there that u prefer

 

Dr.D won the shootout in the YFZ pipe shootout. Check it out at www.dirtwheelsmag.com

 

Out of the three..HMF

 

Out of those three the easy choice would be HMF.

I wouldn't waste my money on just a slip on. Do it right and get the whole system. You have 7k quad on your hands. Do it right.

I have the CHM and like it. Makes very good power, I have dyno charts, and was a leader in one of the pipe shootouts (they don't advertise in Dirt Wheels so wasn't in their shootout). Mellow deep note and not too loud at WOT. The HMF's are very good pipes too but bone-rattling loud. I believe on the YFZ that a headpipe change aside from a slip on is not going to give you any improvement, but I may be wrong.
