I've heard that the '05+ exhaust systems are a big improvement over the previous years. (Sound better, flow better, etc.) I've been looking at exhaust and realize that there are "axle-back systems", and there are "cat-back systems."
Now, I do understand what the difference between these two products are, what I don't understand is what's the added benefit of the cat-back system over the axle-back on our cars? It seems logical to me that the difference is in the muffler anyway, so what advantage is there to buying the extra pipe that runs to the cats? (I also realize [think I do anyways] the difference in x-pipes and h-pipes, I just want to focus on the acutual systems)
For instance here is an axle-back: http://www.partshopper.com/shop/MAC-SS-Mustang-Axleback-Exhaust-2005-2006-2007-GT-m120.html
And here is the cat-back: http://www.partshopper.com/shop/Magnaflow-Mustang-Exhaust-System-2005-2006-2007-GT-m28.html
I know they are different brands, but I was just using these as examples to help illustrate my point. The only benefit I see that the cat-back system has is that it's manderal bent. I haven't looked under my car, so I'm not so sure that the stock system isn't manderal bent. Can anyone help me understand why I should buy one over the other? And, if one is better, is the added cost difference make the purchase worth it? Thanks.
