I was excited about installing this muffler and expected it to be real quiet better than the origional equipment well not so I still needed the resinators. I wish I was told I would need something to keep the drone noise out of the cabin. There are a lot of V/^ engines out there and more testing should be done to eliminate the drone noise and still have better flow.
