Fast service, priced much cheaper than [vehicle manufacturer] or big box stores like [retailer]. Easy to install. I installed this with a Basani road rage mega 2 pipe, the dyno showed a 21 hp gain with this combo and dynoing it with a Screamin' Eagle se pro super tuner it's a whole different bike.

I had purchased this system for my 2007 Harley and I am happy with the results of it especially out of the hole power due to its ability to breath better with this filter.
