If it's sound you want, I'd say just swap out the muffler leave the stock pipes. If you got a magnaflow cat-back, it wouldn't be too much different. Just a lot more $$$$. I like mine, quite at idle and while driving, loud when I punch it. I know yours will sound different. Here is a pic of what I got & a short video
This is probably the closest they have to your car. Magnaflow
If I were to do it again, I'd just swap out the muffler.
