Not only that, it is connected to a 70mm Y pipe with an exhaust that has a similar db rating. To make this even more interesting, I run long tubes, matching the db and rasp TP's give. Holy shat, I know WTF I'm talking about! Miracle! 70mm is 2.75", there are no cats on the market that directly bolt on in that size. However there are at 3". It still works just fine. To quantify my understanding to your issue, I also bought a resonator I can swap out with the HFC. All is takes is a V clamp and two bolts. Now all of a sudden, I can change how loud the car is.

If you can get over yourself and look at my journal, I have links on the top of my page. And I was actually trying to help you out. Let me know when you come back down to earth. I didn't brag about being where I am or doing what I do. I poked fun at it after the fact. My rank is not a Chief and you haven't been on your knees long enough to call me cupcake. Hopefully you actually find what the hell your looking for. I've been there and done that.
