I got the idea after I heard a sound clip from someone else who did the same thing on the mazda3forums. I was really impressed with the sound, so I ran out and did the same thing.

Went to my local muffler shop, and had them remove the muffler and the resonator closest to the rear of the car. And just weld in straight piping in replace. All for 65 bucks. I figure this will hold me over sound wise until I save up for the MS CBE.
