I looked at the Gibson 619901 and the Magnaflow 16679 . I am able to get the Magnaflow for 457.27 plus tax Canadian. I guess I will go with that, Thanks all
2007 v8 I was looking under the truck and it looks like the muffler is part of the resonaitor ? Is that the case ? The pipe that attaches to the exhaust manifold flange ( Driver side ) looks like it is ready to fall off as well ( Rust ) . I was thinking about maybe going with a Magnaflow...
I called the dealership. Mentioned it is a non servicable part. He didn't have a part number. I guess it only requires changing if you are having problems.
