This fit my 2003 Mazda Tribute LX perfectly. I installed it and less than 20 minutes, the hardest part was getting the rusty old piece of garbage out. I used a Sawzall (that took about 35 minutes to cut everything out) and replaced the catalytic converter, muffler and resonator at the same time. Everything bolted together super easy and the car sounds excellent!
