Honestly there is really no need to dyno this. There have been numerous dual 2.5" exhausts dynoed and we all pretty much know the results, very little gain. I'll ask the owner if he wants to do a pull to see what the change was, but its not a priority. He just got dyno tuned a week prior so this will be a fairly comparable test.

If we get more then 15 RWHP I'd be impressed. I like it for the sound and weight savings over the stock set up. If you are looking for a power gain there are better places to spend 1k.
