Everyone seems to forget that our SLP set ups are MODULAR, if the lm1 is too loud/not deep enough, just get the lm2 mufflers or powerflow mufflers, they slip right into place at a fraction of the cost of a whole new catback

SLP I's are loud and raspy, not really that deep. Try going with the Magnapacks. They are the sound you are looking for, and paired with your MRT catted H it will sound downright mean. Here's a clip : http://s35.photobucket.com/albums/d1...agnapacks3.flv

+1, on Magnaflow catback. Mac or Bassani would sound great to.
