I'm fixing to order one of your O/R X pipes for my 2011 GT however Im already running a JLT/Evolution 93 street tune. The question is do I need an updated tune after installing the X pipe ? I would like another Lund tune but a little more aggressive just for track use, I'm not chasing Dyno numbers and wanna still keep it safe. Thanks for any info in this matter.
