Doesn't sound as godly as the Fabspeed IMO, but well-engineered with some actual gains. Go SOS! Sound comparison starts at 2:23, and the tech stuff is the first 2/3 of the video.

 

Here's a take of the DP's and valved exhaust from SOS.
Sport +. About 60-70% throttle.

 

I need to stop by there again, practically in my neighborhood.

 

I fixed your video link, estradaccord. That sounds pretty damned good. Is that your car?

PS, Ken, when did you move to Arizona?

 

Last month!

 

Thanks for the fix. No, it is not my car. It's our company "race car". 1 of 3 I get to work on and drive here at the office.
The owner likes mods and racing and I help feed into his Honda & Acura habit as much as I can.
We just put BMC filters on, so with SOS DP'S and valved exhaust the turbos whistle even louder and the exhaust note is very intoxicating. Amazing car.
