brands5.0 Posted August 22, 2006 Report Share Posted August 22, 2006 hennessey performance does not have a really good rep. it seems on the net .And there are a lot better people out there that proved them selfs with the 03-04 cobras. Everone should stick with what was learned from the past cobra owners and go from there. I know ill go with guys like http://www.lightningforceperformance.com/ http://www.johnnylightningperf.com/ We should start a list of companys when parts start coming out Link to comment Share on other sites More sharing options...

Hennessey stuff gets trailered home a lot if I recall correctly. bj Link to comment Share on other sites More sharing options...

One mag even made a joke of it a year or two back. Link to comment Share on other sites More sharing options...
