chillyw2 09-23-2007, 02:19 PM just go to a muffler shop and have them put in a straight pipe. Only $50 on my truck. chillyw2 09-23-2007, 02:20 PM The sound is a little deeper if you retain the cat, but not unbearable inside the cab.

Do you have a LLy or Lb7 beacuse most lb7's that are not cali trucks don't have cats to begin with Lucky 13 09-23-2007, 05:26 PM i have an lb7 with no cat and how much power/mpg gain will i get GMCJOE 09-23-2007, 05:56 PM No Muffler and not cat is quite a bit louder than just no muffler. We deleted the muffler and cat on my buddies 06 LBZ and thing thing screams at Wide open! Idle sounds like a jet engine. Turbo whistle increases as well without the cat and muffler.
