But I had to mutilate one to remove it (demon bolt!) So now I am stuck with my HFC's and need to decide what to do. I am thinking I might just have to get the Stillen CBE and call it a day. I really don't want this kind of attention and any fix it tickets!

So my question is, what can be done to quiet it down some other than stock cats? Would resonators added to the mid pipes help?

As a side note this exhaust is top notch! Fit is 100% perfect and the quality is amazing! I really want to keep it but it's just too loud for my taste.
