Will the Doctor Speed cold air box fit on the GXP since its the same engine as the GTP? Im looking to mod mine when i get it and any info on this would be helpful. Also does the stock version come with a performance exhaust or do you have to get it dealer installed?

yes they emailed me saying the dr. speed will fit my 2008 gxp with the 3.6.
and the performance exhaust is an $900 extra unless you can get 20% off the top.
