How to make the 2.3 faster?

[cmedrive]

I think you misunderstood. I'm not saying a muffler will add power. What I was saying was that if you buy a quality, name brand part, you'll be happy. Mazdaspeed, AEM, Fujita, Injen, Borla, Magnaflow are all available for our cars and most likely through a site sponsor.
This is a popular topic, btw, a quick search will probably bring up a number of threads with more info.

Thanks. My 3 GT is suppose to arrive Thursday afternoon. I can't wait for it. (dance)(bowdown)(drive2) This weekend, or next week, I will have to get the windows tinted and put the XM Sat. into my vehicle.

All I have to do now is fine Mazda clubs in the San Antonio area.
