I am going to be putting an exhaust on and I was wondering if there was a noticeable power difference between the single and dual out witha Flowmaster 40 series..
I am going to have a cat back made and want to get the most performance possible. Just curious if one or the other has advantages or disadvantages.
Thanks in advance.
