    Post Bend It Away

    To the rear of your clutch, I think after the Converters, there is an aluminum shielding around the pipe. The shielding is very close to the pipes and is probably hitting it due to vibrations. Take a heavy duty pair of pliers and bend it away from the pipe. I had this problem upon the installation of my pipes. Installation repositioning occur when they adjusted for the well. It's an easy fix for a lousy problem.

    Happy Easter,
    Matthew

    Does your car have Longtubes? If so they might be hitting the floor. If thats the case you'll need to get some hangers from the mufflex exhuast website.

    it sounds like the pipe is hitting the floor board. Look under there on the drivers side and see how much clearance you have. Like was mentioned, the mufflex bump stop would help with this.
