I've seen Polak's dyno vid, but i was wondering if someone with a NA turboxs setup could make a clip similar to the one adrian-1 did with the turbo? also, is there much drone with the system? I'm also interested in the HKS setup with a midpipe.

I havent heard the xs exhaust in person but i've heard the HKS Legamax exhaust with RP super cat and I must say its one of the best sounding combinations out there. Too bad I never shot a video of it. Compared to other high flow cats I believe the RP supercat sounds the best, not only that, you can still pass smog.

Here's a video of my HKS exhaust with racing suction. I do not have a hi-flow cat installed:

Keep in mind, these videos were shot directly after installation. The sound now is a little more different

i have turbo xs na setup it sounds the same as the his turbo set up but louder

 

I had the HKS Legamax exhaust with the RP Supercat and it did sound pretty awesome! The only problem is that (in my opinion) it was a little loud for everyday driving. With just the HKS Legamax, it was 93dB and with the HKS Legamax and RP Supercat it jumped to 105 dB! If I put it back on, I'll see if XDEEDUBBX will take a video of it.

FYI- In Japan, HKS just released a Metal Catalyzer for the RX8. This 65mm SUS304 mid-pipe includes a 150 cell metal catalytic converter along with a sound resonator. According to Japan, this combined with an HKS Legamax exhaust is only 95 dB. This could be a more expensive option for you!
