Hey guys just wondering which will give me more power, a cat back exhaust system or true duals? Someone told me you lose power with true duals? Is that true?

I just put on duals with flowmaster super 44s and cats still In sounds great no loss of power

I would also like to know this answer. I've been thinking of those two but cant figure out which one.

These type of exhaust mods alone will make almost no difference in performance.But they sound nice. Combined with other mods it can help. If intake air is what's limiting HP, getting rid of more exhaust does little or nothing to improve it.

Thanks guys I'm gonna go with the duals!

If you do duals make sure you spend the extra cash and get an 'X' pipe not a 'H' mid pipe cuz you get better exhaust scavenging meaning a lil more power. Also if you want more torque get 2.25" pipe diameter, if u want more hp get 2.50"
