I'm not looking for something obnoxious, just something I can hear.
Also, I couldn't care less what other people are thinking as I drive by.

I cut and pasted a recent response that I gave to a similar post:
The oem exhaust is very restrictive in all regards. However, one must take a thorough and methodical approach toward improving the system. Otherwise, you'll end up with not only CEL's, but a loss of power as well. Both the pre-cats, as well as the secondary cats involve the greatest amount of consideration. Contrary to race applications, it's been my experience that some degree of back pressure is essential in order to maintain low end to mid range torque. With that said, somewhere in the equation you'll need to factor in cats - as either part of the headers or mid-stream. That gives you two options, you can opt for a set of custom headers that involve longer, equal length primaries that flow through a merge collector straight through to the flange that incorporate low cell,, high flow cats attached. Or you can forgo the header and cat combination and source some individual high quality, low cell cats and position them mid-stream, keeping a set of high quality headers independent. In either case, you looking at considerable money to accomplish this. As far as the oem catback is concerned, you'd be better served by using a coffee can with a boat anchor attached to it. On a positive note, however, there's a limitless number of aftermarket catback exhausts that run the gamut in terms of price - that will prove to be a worthwhile upgrade. If for no other reason than weight savings and better sound.
