Bought a car that had loud exhaust . did some measurements and bought these mufflers . I have my own 2 -post lift so it is an easy access to work and this was an easy change over that did quiet down the noise . All bolt on and no welding .clean install . Have to understand that with full tube headders that noise level will be louder than stock single exhaust but far better than before
