apexi active tail silencer
here's a link to it
http://www.prostreetonline.com/news/...tail_silencer/
this guy dyno tested it compared to a cheap silencer and no silencer at all. interesting. the test car was a 400+ whp skyline, which is a 2.6l straight 6, which is in the same ballpark with exhaust flow as a stock REW i'd say.

has anyone used it? i have a cheesy cheap exhaust on my car right now and i'd love to get a nice N1 style catback, but they are just too damn loud. anyways, with this, it seems to quiet the exhaust down quite a bit and not lose nearly as much power as you would from a standard silencer.

I have the 90mm one sitting in my garage. I used it for 2 months on my WRX, but in the end decided to switch to a completely different exhaust.
It definitely made things quiet while putting around and opened up at WOT.
If you want it PM me. (It was $145 brand new + shipping).

They made it so you keep that low end back pressure and it fully opens at high rpm, so you gain high end horsepower. That way, you have the best of both worlds.

Yeah, everything time I see my buddy with his HKS Hiper, he would always try and get me to swap exhaust with him.

+1 to the ECV. what i'd be interested to know is if we can use ECV to control the backpressure instead of having a highflow cat on the midpipe to help with boost creep ??

I have two of these (90mm non-turbo n/a) on my dual N1s. Much quieter than unsilenced. I don't have dynos with them on or off but it doesn't seem any different than before I got them. I think this ECV valve would probably be the best option. Sometimes I wish my car was loud again!

turbine wheels and restrictive turbine housings provide more than enough backpressure to prevent the loss of low end torque.
standard silencers for N1 style exhausts flow horribly, so they made this new silencer to help with FLOW while keeping the noise down.

does this silencer work with any exhaust, or is it just apexi specific?
I looked at the website and it seems like they offer it in 115mm and 90mm (turbo n1, gt spec, and n/a n1 respectively)
Now if I have another exhaust with a similar design (jic or other canister type) and the tip matches, would this silencer work? would anyone have an answer to this? Thanks.
