I have a the 50 series flowmasters with offroad h and bbk shorties and I love the deep sound. People think the car sounds like a car with a bigger than 4.6 liter engine. Before I added the bbk shorties I had that dreaded trumpeting sound that truth be told I hated. After I put on the headers the sound changed completely. Deep and bassey and no more trumpet. But what I like might not be for you. Its all in what appeals to you.
