Well back in the day I had a 01 4 cylinder AT tiburon and I loved it.. well time went by and so did the miles. I soon relized it was time for round 2. So, just a few weeks ago bought a 04 tuscani elisa 2.7 tiburon and I love it. And yes I'm already dropping money in this car to make it better :) I'm just up in the air about what header to get.. I really like the arc and dc headers, but how good is the shark brand?? I don't care about the price like everone else, but I do want good quality in the ride.. plz help me decide
