So I'm really interested in the JRE 415 rwhp package Jannetty Racing is offering, even though they haven't responded to my pm's and email
Anyways, my question is whats the advantage of long tube headers over the stock set up? I like the idea of high flow cats because I have had them before in other cars so I know about those. I would like to get a complete system including headers but I just want to make sure its money well spent. I have an LS3 M6.
