I have a Jardine exhaust that is a direct bolt on cat back for the lightning. I think they only made it for a year. I bought it 2 years ago and installed it myself. It looks just like the mac exhaust and i can describe the sound. When you start it up it is loud, driving around it is mellow and wot it screams. Interstate it has a very slight drone when you turn the music off but when it is on you cant hear it. I would like to sell it because my full exhaust goes on monday. But would anyone be interested in buying it and any offers will be considered. Also i will get some pics up soon. I bet it would be a beast with highflows cats or catless set up a well.
