this is from the Perrin Web site.

and here's what JSC Speed says about it:
http://www.jscspeed.com/wrx/exhaust/...tubesystem.htm
I have the 3" dual tip/single tube exhaust. I love it, it sounds excellent and if you get the sport tone the mid pipe has a resonator so the sound is MUCH quieter than the straight pipe version (which I also have). It also is a very aesthetically pleasing system, and VERY solid. I believe it has 1/2" flanges...uber beefy. The Dual tube version is mostly for race applications where there are huge turbo's and extreme tunes involved.
Dual-Tube™
For WRX and STi owners a specialty system is now available, using dual 2.25” exhaust pipes to carry exhaust gasses and unwanted sound to the rear of the vehicle, and exiting through a 4” slash-cut tip. This system is designed for clients with far higher horsepower than stock.

and here's what JSC Speed says about it:
Designed for WRX & STi owners pushing large amounts of power from aftermarket turbos and other modifications, the Perrin dual-tube exhaust is designed to outperform all other catback exhausts on the market. At the downpipe, the Perrin dual-tube exhaust begins with a 3" diameter pipe, then splits into two 2.25" tubes for optimal flow (4.5" overall diameter) which continue all the way into the muffler for optimal flow. The Perrin dual tube WRX & STi catback exhaust system is designed to give the flow of a 4+ inch diameter pipe without the fitment issues, and it tucks up underneath the car nicely.
While the Perrin dual tube exhaust has exceptional flow, it is not that much louder than comparable catback exhausts, making it a great all-around exhaust for your WRX or STi. The Perrin dual tube exhaust is full stainless steel for longevity and quality; you will not find a better exhaust for your big turbo Suby!

so then out of curiosity.... how do you think it would perform and soundon a stage 2 WRX? would it sound similar to the single tube?

My guess is that it would sound pretty much the same, but to be honest I think that might be too much flow for only a stage 2 WRX. The dual tubes equate to a 4.5" diameter single pipe, so unless you are running something like a GT35(R) or a Superzilla or something really big, I would suggest the single 3" version. If you open up the exhaust too much you will gain some HP but start to lose torque.

i haven learned to not listen to things on forums anymore...
learn from the creators, or the best...
not from random people on forums..

the dual tube(i read up some lol while trevor thought i was calling him a dumbass i did what he should have done, gone to perrin) is meant for something with a huge turbo, the stage 2 wrx still uses a stock TD04 which is very small and doesn't need the huge piping... the dual tube creates more flow for the GT turbos for helping spool.. but adding it to the td04 only creates to little of back pressure and causes a lack of torque(which will create a feeling of lack in top end).
happy trevor, should have just read perrin and it was easy to understand..

dude... Ryan... i never said i wouldn't talk to the creators... actually i did better than you and talked to the tech department for perrin for the past few days... ever since i started this forum.... i know how things work and according to perrin the exhaust still creates just enough back pressure for the TD04 to run to its potential but it allows for bigger turbos or cars with 350whp+ to run at a more optimal level... i will probably post the e-mail convo for everyone else to see what perrin said, but the reason i was asking on the forum is to have peoples first hand input if they happened to have the exhaust...
