You can buy a cat-back exhaust that is factory-made for your car, and have its flange bolted to the flange of the front section. Or you can buy a separate Magnaflow muffler and have a muffler shop cut off the old muffler and make up (bend) some piping to weld the Magnaflow onto the remains of your OEM cat-back.

In my opinion, the Magnaflow will be loud, and the work likely to be crude and cost almost as much a factory-made cat-back.
So it is a "fit and finish" issue mostly, or do the cat back systems like the Remus or SuperSprint sound better than a Magnaflow muffler? I can get a Magnaflow that has the right size flange and twin output for about $215 (it was $150 just a few month ago) and I figure $100 to have it installed.

The Cat back systems I have seen mentioned on the forum seem to be $600-$1000. For me that is a big difference, but I don't want to just be cheap. If there really is a significant diffrence in sound quality or performance, I will just keep saving for a bit longer.
