Deleting the stock primary cats will give you the most power gains than any other single mod without going the FI route. Add to that an awesome sound and a 50 pound loss which is also nice and we are talking about a good deal, IMO. Unfortunately I have not dynoed my car, but it definitely feels faster.
Here's the link to my impessions on the Akra Evo. Feel free to ask any other questions you may have.
