I recently purchased a 97 GTS and it has the Hennessey 500 package. It has intakes, smooth tubes, headers, cats, and exhaust, and last but not least, the Hennessey 500 floor mats. Does the Hennessey 500 have any other upgrades or is this it? I just know this is what the car was advertised as having and I was just curious what else it may have. I am a Viper newbie and long time fan (its the only car I have ever wanted), but from browsing these forums I can tell John Hennessey is a polarizing figure. I just want to know all about what I am getting and what you guys think about it. Thanks!
