I know everyone has differetn exhaust... now from perforamce, which exhaust would you get the most power out of.... or would you get an equal amount just differen type of exhaust?

 

you will get the most power out of a cat back exhaust. Axlebacks are generally just the muffler-back and just add noise. Catbacks reach far back and open up a lot of the exhaust for more airflow.

Of course though, you will get the most gains with a full exhaust system. This includes headers, an s pipe, and your catback.
