No problem, I will post the differences. I was surprised to see the variations myself. Not a huge difference but the stick cars will be favored. This is probably what accounts for the slightly higher rating the R/T Stick receives over the auto. The SRT-8 hp rating does not change but the difference between the SRT-8 auto vs stick exhaust is less than the R/T versions. I will dig the info out and post it on this article.
