RX8 exhaust with no muffler or resonator
First was muffler removal. Then went ahead and removed the resonator that is right behind the catalytic converter. Note how the idle always settles back down into a distinguished noise, now that there is no resonator smearing the pulses. Keeping cat for emissions, and backpressure to open the last 2 of 6 ports. I'm waiting to post some higher rpm sounds, once engine #3 is broken in. This video is engine #2, I parked it for 2 years and only had a couple fillups. Unfortunately I'm on engine #3 now, never fully broke in engine #2 for higher rpm sound capture.

SP Greddy Exhaust Rx8
quick vid of the sp2 Exhaust from greddy. I had to have the Exhaust hangers modified to make the Exhaust fit. I took it to a local shop in houston. you can get longer rubber hangers as an alternative too but i went with something a little more sturdier.

Turbo Exhaust Whistle Test
Here is a test of the turbo Exhaust whistle on my Ford Focus. The turbo Exhaust whistle is supposed to make a regular car sound like it has a turbocharger on it. The turbo Exhaust whistle fits inside of the Exhaust tip on a car, and it makes a whistling noise when you rev up the engine. You can buy a turbo Exhaust whistle for less than ten dollars on eBay. Watch this video review of the turbo Exhaust whistle to see if you need one.

RX8 With Straight Pipe and GReddy Cat-Back
Just thought I'd upload a quick vid I threw together the other day, nothing fancy. I just made it to try and illustrate the sound of a Mazda RX-8 with a straight-pipe (no cat) and GReddy Cat-Back Exhaust. I placed the camera on a small tripod about 3-4 feet away from the tailpipes to avoid audio distortion. Honestly, I think I'd like a much deeper and less raspy Exhaust note, maybe a Borla system. [EDIT] - Sorry for the slightly weird distortion effects at the beginning, that was the YouTube anti-shake feature. Panning smoothly with your hands after a Monster Energy is difficult. -Also, someone asked what the rims are; I mistakenly said they're 10" wide in the video, they're actually 9.5" wide, 18" Axis Halo rims.
