Which exhaust would be better?

I recently purchased a wreck with a camed & ported motor, 5 spd, and a true dual 2.5" exhaust with resonator and bullet mufflers. My present exhaust is a 2.5" to 3.5" to 2.5" with resonator and oval mufflers. The true dual resonator is about 2/3 the size of my present one and my mufflers are Magnaflows. Which one flows better for my motor and if the true dual does is it worthwhile to swap it?

The resonator in this case is the most restrictive portion of teh exhaust. See what your current resonator flows and then the new one. That will give you your answer. Will that equate to a gain or a loss..No lida
