the new system is in place, and i like it a lot. used a long 4" truck muffler, straight thru. 4" down pipe and 4" tailpipe, finished with a stainless 4" tip. the soun is deeper in pitch, not a lot louder than stock. sure can hear the turbo ot the pipe. a friend said it sounds like some of the pulling trucks at sled pulls. wasn't convinced i was being truthful about the engine still being stock. for anyone wanting to open up the exhaust without being too loud, this setup should be considered.
