Review: I purchased a performance kit. Includes HMF exhaust, K&M filter and a HMF fuel optimizer. My new HMF exhaust for my 4 wheeler was just to loud so i ordered this. As per instructions I removed end cap and installed this core and my spark arrestor. The core fit into a machined groove that was obviously there for this core. Without the spark arrestor i could imagine the core might rattle. But instructions clearly indicated the proper installation. Tightened bolts and off I went. Now it has a nice rumble but is not crazy loud. Core did its job. Before the core install my machine sounded like a race machine. After core install i think it sounds more like a muscle street machine, more in tune. Personnally i think the exhaust system should come with tuning options included. I'm happy with the sound and performance. Hope my neighbors don't mind. I recommend HMF products including this one. This is my first HMF set of purchases.
Review: Easy to install and definitely reduced noise

So far so good. Easy install and actually significantly reducing the volume of this pipe. I live in the country and appreciate the reduced sound, so to my distant neighbours lol. Before you could here the pipe for miles, big difference.
