[QUOTE="Lloyd Chaudoin, post: 1006946, member: 70555"] In my opinion that is the wrong muffler. If I remember right our exhaust diameter is right at 2 3/4". You would be better having an exhaust shop expanding the exhaust into and out of the muffler rather than crimping/swedging it down and restricting flow more. Also the case size you picked will not soak up a lot of the sound waves for a nice quiet burble at idle. I used a #12589 Magnaflow I believe. It is a 3" inlet and outlet and a larger 5 x 9 x 22" case. I opened mine up and removed the resonator. But, my truck is not absolutely quiet either. It can be easily heard when started up early in the morning. Not obnoxious but definitely heard. I say install that muffler and keep everything else, it should be what you described as needed...
