Duals back from cats? Good idea?

[redeknightjr]

I have 09 hybrid and looking to do dual cat back with dual magnaflow. Any knowledge on this any one?

It's been awhile since I've been one , but I did the true dual rear exit with magnaflow mufflers! It sounds good. I also have Volant closed Cold Air Intake. Now it backfires! Should I go back to factory intake?
