I have the Mazda3 GT with the GFX package (automatic). Is there a
place that sells performance enhancement parts for this model?
Performance exhausts (not to loud). Cold air intakes or other such
things.

 

obwon - check it out. Not too loud at all. I had a Magnaflow in my late 1997 Mitsubishi Galand 2.4l 4 cylinder - sounded so so so much better than what it replaced - a Tsudo dual slash tip. I noticed an increase in bottom end, but not mid to upper end. The Tsudo was clearly set up for top end though. It resonated way too much in the cab. The magnaflow did not - it was very sweet - it has a much lower tone and a good rumble - even for a 4 cylinder - interesting.</P>

Mazda performance parts are available for the new Mazda3 on www.shaneracing.com - I have never bought parts fromn these guys buy they claim to have Dyno tests showing some good hp increases with the exhaust systems specifcally. Good Luck.
