Science of Speed Downpipe and Exhaust
 

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. :thumbsup: Is that your car?

PS, Ken, when did you move to Arizona? :what:

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.
