I've never seen the chambered axlebacks they now have. I would bet that will sound really good without being too crazy loud. You should contact SW and ask about the length. They may have sound clips too. I say go for it!
I have heard sound clips of the SW chambered exhaust but only on stock cars or paired with the SW headers and x pipe. I have kooks headers and H pipe so was just wondering if anyone had that combo. I will make them work even if some cutting will need to be done. I guess I will be the one doing the experiment ha.
