I have a new HMF Penland Performance Series exhaust for a 2007 Yamaha Grizzly 700. It may also fit 700’s from different years. I also have the Quiet Core insert that is included. I bought this to try and found out it was too loud for the area I typically ride in. I love the sound! It sounds wicked! It’s just too loud for where I ride. I put this exhaust on and ran it for a few minutes and decided it would not work, so I bought the Quiet Core insert in hopes it would be more suitable, but it did not quiet down enough. I ride a lot at the lake during the summer and I try to be considerate of my neighbors while out late, so this would be too loud. It’s a very nice exhaust and costs nearly $400 new for the exhaust and insert, so the price I am asking is very reasonable for an incredible sounding exhaust made in the USA by an American company. I’ll try to post pictures when I get home, or I can text them to anyone interested.
