Default Stack Size

I am looking to run dual stacks in my '04. My question is what size would be best? i was looking at 6"-8". i have stock exhaust now so i dont know if those to 8" tips would relieve to much backpressure, or no. hopefully if all goes right i will have a quadzilla adrenaline chip within the net 2-3 months to, so idk if that might help. please send them forward if any videos or comments

8" sounds sweet at about 70mph.
