yea everybody is right cause i did it by my self with my cat back as long you have all the parts needed to put it together than you can put it on your self. but if you want to have it install the right corrcet way and to make sure that nothing goes wrong go to a shop the best is pep boys or minake you'll get good discounts. just take my advice you don't want to have your exhust coming off at a speen bump or a hole in the ground.... i should know i seen people do it them selfs.......
