i am changing the factory exhaust to the magnaflow catback exhaust. magnaflow offers 2 different types. one is a single 3.5"(p#16771) and the other is 3.5" to (2) 2.5"(p#16772). which system works better for the 6.2 liter? according to magnaflow tech, they told me the single will flow better at higher rpms and the dual will have better bottem end torque. also, if someone has one of these kits, does the tips turn a goldish color? thanks in advance.

 

Really a educative and informative post, the post is good in all regards,I am glad to read this post

 

I'm thinking of changing my exhaust as well, I'd like to know which one too!
