"I had Lou's install an x-pipe with Magnaflow straight pipe mufflers that I saw on a video clip. The system rocks with a mean low end rumble when idling and really screams when you step on it!!! The install was done perfectly and I have shown everyone with the response of WOW!!! I will be back to have c.a.r.b legal headers installed next. Thanks for a great job!!!I had Lou's install an x-pipe with Magnaflow straight pipe mufflers that I saw on a video clip.
