Hey man, you are going to have loads of low-end with that setup. Trust me, I run the same size piping with a flow-through muffler and no cats and run 1.92 60' times on stock tires and 8.7 1/8th miles. I always recommend 2.25 into 3" as the nest performing set-up, along with a few other members. I have seen a lot of set-ups run at the track, the cats IMO aren't really going to help with velocity. IMO coating isn't going to help enough either. I did not get my headers coated and is has not hurt my performance at all. There really is no way to keep the velocity up with larger piping, thats why some of us always try to steer people away from y-pipes such as the Banks. But in any case, you will not be losing any low-end power with that set-up. As a matter fact, you should have too much to use LOL. Give it a try and report back to us
