Thus far, I've decided I don't want their mufflers. I'm thinking Dynomax because the Magnaflows are stainless. Just don't see the need if the rest is not stainless. I haven't decided on 3" or 2.5". I'll be running the 360 for a while longer but I want it setup for the 408. I also need some high flow cats. From what I can tell so far, the cats and pipes get kinda close to the trans and fuel lines. If so, what have you guys done to address this? What size and offsets of mufflers are needed? I want to keep the exhaust sounding strong but not drawing too much unwanted attention.
