Exhaust question

[Coenen93]

Sorry I haven't posted lately I just got promoted at work and have had no time for fun things lately. On to my question on my 78 LeSabre Sport coupe it has just single exhaust at the moment and I was thinking about adding duals but i don't know if it would make much sense on a factory (as of now) turbo v-6 or if it would even sound good. Any opinions or experience in the area would be appreciated. Thanks in advance.

Cat back dual is fine but you can't run a true dual system. To get better flow you need a bigger downpipe (there's a post in the how to section on how to make one), a cat removal or high flow one, and then 3" single or 2.5" dual cat back system.

Awesome that's kinda what I was thinking and i don't have to worry about the cat. They seem to "fall off" most of my vehicles.
