Hmmm was definitely considering an exhaust that would give the 2.7 a nice sound as well as not affect the departure angle. Of course a good HP gain helps too.

This is the first post of it's kind I've seen that mentions dyno gains, well done! I assume the maximum gains were on the 2.7?

Edit: It looks like testing was done on the 2.7, but the axle back FlowFX systems free more power than the cat backs? Is that a typo?

That Outlaw Dual Axle back sounds really good. I think its going to have a lot of drone though.
