Really woke up the Bike, Great Sound!!

Comments On Apr 19, 2013:This Pipe Sounds and performs AWESOME!! I installed this pipe on my TRX400ex with the Pro Design Pro-Flow Intake Uni Filter, and air box lid-off. I can now pull the front wheels up no problem in 3rd and 4th. This Pipe is exactly what I was looking for, the power is such an incredible increase and just sounds totally stellar. The only issue I had is that the HMF Jetting kit should have come with the infamous "D" tool to adjust the carb, but aside that minor detail I am very happy with this purchase.

Best bang for the buck 400ex

Comments On Jun 04, 2011:I put this on my 400ex and love it and you will like the way it makes your machine sound as well. HMF sounds as good as any of the other aftermarket exhaust pipes you will find out there and you can feel the power it adds as well. Go for it you won't be disappointed at all.
