I don't have rasp now but when I put my headers on I will. I've heard my car with the rear resonator in place and the ZHP muffler after it though, just not with eBay headers which is my concern. I'm going for a little more volume but more aggressive as well.
I only have one resonator, and also I'm not looking into buying a new exhaust.
