06 Impala muffler

Ok, I think I figured out what I want to do now. I'm going to replace the whole exhaust system and can do this for around $450 in my driveway. I'm going to install a magnaflow highflo direct bolt in cat and the walker cat back exhaust which is also a direct fit and comes with everything I need to do it. That way I'll get a few more horsepower and an exhaust which I need that should last the life of the car.

Try the "W body store" probably want to get a high flow cat also, and a cold air induction kit.
