    Great quality

    I recently purchased these from another site and I am impressed by the quality of the pipes and sound. I gained a louder growl with some extra crackle along the way. Overall it only took about an hour to install, I had to do some cutting due to my stock H-Pipe being in bad condition. Other than that the installation went smoothly.
