I am trying to design an exhaust system for a 313 HP/390 TQ 350 I am putting in my 95. I want to use a dual 2.5" into a single 3.5" system, and want to figure out if that will be overkill or just right.

I know some of you will tell me that it will work or that it will not, but I would rather let the numbers tell me whats up.

Thanks.
