Well, I did it! I had the stock oval muffler removed and a straight pipe installed. My 07 Hatchback has a cat, another cat, a resonator, a muffler and another resonator in the exhaust system. It was WAY to quiet so I had the muffler removed. I was really worried it would be to loud for me removing the muffler, didn't want much more sound. It's perfect!! When Mike (shop owner) started my car to pull it on the rack, I was standing about 10 feet behind the car, didn't hear a thing from the exhaust. When he started it after he was finished, I could hear the exhaust. It's not much louder and 99% of the people who hear it will think it's stock. I can now actually hear the exhaust at higher rpm's which is all I wanted but it's still pretty quiet. I'm pleased!
