If all goes well we will have a set of 2" with cats on my car by next weekend. I will also be doing dual 3" electric cut outs pre AFM valves. That will allow us to see what the headers and cats are worth by themselves and what they are worth if you went with a cat back. I like the stock NPP but would like a way to bypass it. We are going with 2" for my set up since I will be going with the blower eventually.
As usual, we will be dyno and track testing the headers. There is another track rental on the 21st that I will be at if the weather holds. Hopefully some high 10.7's will be in my future. I am trying to get my converter and rear replaced early next week at the dealership. I also found some more power on my set up with more snout work on the IM and some more work on the back of the TB. I gained 5/7rw with the extra work. Those combined should be worth a 10th or so before the headers.
