Hi all, I went straight pipes about 3 months ago and it was fine for a while but that constant drone and vibration was enough for me to search out a better way. I went to my local midas shop and talked to the manager there and he said that i wasn't the first straight piped diesel owner that he has seen. He recommended the ravin performance muffler,long story short it sounds great. I would recommend this set up too anyone. straight pipe into ravin muffler turned out in front of rear passenger side tire,with a chrome 45 degree cut 4inch tip. The sound is louder than stock with a throatier sound and no vibration.
