INSTALLED SPORT EXHUAST TODAY
I installed the "Mazdaspeed" Sport Exhust today. First I want to say the quality is outstanding. I can't beleive I only paid $200 US for it.
The install was pretty easy, even for one guy (me).
I only ran it for about 30 minutes after install - but here is my opions so far:
It is louder than stock. Surprisingly it is bearly audible at idle - which is something I really liked about the stock setup - the Sport Exhaust did not change that. There is more of a noticialbe "drone" espeacially after 3,000 rpm. Although this car is my daily driver, I bought the car because it INVOLVED me in the driving experience - and the Sport Exhaust just amplifies this experience. When I drive this car I want to just plain drive it, not carry on detailed converstions with my wife, etc.. So for me, I like the pipe, and will keep it. (I will run a dyno test in a couple of weeks and post the results from that.) For me, the only change as far as usability goes for the car because of the Sport Exhaust is that, a couple times a year I make a 600 mile drive (round trip) to visit my folks. With the addition of the Sport Exhaust I guess I would think twice about taking my P5, I may think about using my wifes Impala instead. So for the couple guys concerned about noise levels, I would strongly suggest trying a test drive with someone that already has one - maybe work with your delaer on this. If you think it is going to be too loud - spend your money on a short ram or cold air intake. They will give you a little performance increase, make a little more noise, but not a lot more noise.

PS - My new exhaust has the "Mazdaspeed" etched on the tail-pipe.
