found them on ebay under 'nissan muffler'. They'll arrive monday or teusday. I'm going to install my jdm downpipes and then take the car up to a custom muffler shop and have them install a 2.5" set of pipes 'clean' all the way back to the cans. The mufflers are seamless, stainless with a lifetime guarantee, and probably as good as what greddy, stillen, or anybody else sells at their astronomical prices. The key is to buy a quality can and then have a quality custom shop put them on. When I get em I'll post my quality control audit of them :).
