Since we have the same truck (I have a CC) - can you tell me the model number of that muffler? Also was it easy or did you have to weld?sligsta said:I just swapped my stock for a magnaflow. F*****G AWSOME. I read that you gain 8WHP and 14lbs.WT. I don't know if it's that much but it is a noticable difference. It's my first and only mod so far and I can easily lay rubber with both rear wheels now. Can't wait for my 2 degree advance and CAI.
