Am thinking of getting an HMF Utility Series pipe for my 2007 AC 650 TRV. I had great results with the HMF Utility Series I put on my 05 Suzuki Vinson, so I am committed to the brand and series, but wanted to know if any of my brother AC riders have had any issues with this particular application.

 

HMF claims the biggest HP increase of around 10% and I have never heard any bad things about them.....I have heard negatives on other brands.....I am ordering my HMF this month.....HMF is also bringing out all new systems in JANUARY but I cant wait that long.....I would like to see how they are going to stack up anyways before buying one...
