Performance wise, any difference between getting just the mufflers or the whole cat back.

if your going for performance, id say at least get the cat-back or a cat-back and h or x pipe.

Definately get the cat back or you will just be wasting money. I just had 2 chamber flows welded in and wish I had just waited till I had the cash for the whole cat back. I wasted the money having the mufflers put in since I will be ripping them out to put in a cat back anyway.

I have replaced the cat-back on my old GT, and my new car. You can lay the systems side to side and see why the entire system would be better.

Smoother mandrel bends, and they just look better.
