The factory Porsche sports exhaust system on my 911 996 Carrera was rusted and in need of replacement, so I've used the opportunity to turn to aftermarket options in order to provide a little more bark to my 911's soundtrack.

I went for the Dansk Sport exhaust, a popular choice among many Porsche 996 owners. But is the system any good? I find out with a direct head-to-head comparison between the factory setup and aftermarket system, featuring before and after videos of start-up, rev, pull away, and in-gear acceleration all with my own 911.

What do I make of the change on my 996? And which system do you think is better?
