As often as someone new to mopar wants to get more power out of their car . Thibgs also change once in a while , new designs/products . Besides that's what this forum is for , otherwise just use google and shut the doors here , no ?
Dougs and TTI are best , but I went with Hedman tight tubes with really well made 2 1/2 inch SS mandrel bent pipes from the collectors , flows really well , regular starter no mini needed easy to install remove (15 MINUTES IN AND OUT ) , plenty of ground clearance . For me it was "best" . Link to more pics http://www.forabodiesonly.com/mopar/showpost.php?p=1437563&postcount=121
