I have the nismo cat-back exhaust and now i'm looking into the APS test pipes. I'd like to hear it before I buy it. DOes anyone have a video or soundclip so I can hear how they sound with the nismo catback? please and thank you,

Ummmm can someone at least describe how it sounds hehe.

 

They should sound basically the same as any other non resonated test pipe paired iwth the nismo exhaust.

 

I have nismo exhaust,test pipe, and topspeed headers on my car. Any gains?Definitely. I raced a slightly modified WRX effortlessly,like walk in the park. But,I can barely stand with the raspiness and vibration above 2500rpm. I am runing with Crawford cats instead of test pipes right now.My friend has nismo exhaust and test pipes with stock headers on his coupe. It also sounds very nice,there is slightly raspiness above 2500rpm,but not noticable inside the car.
Nismo exhaust sounds a little deeper than stock set under 3000rpm,but produce very high pitch tone above 3000rpm. I have ever tried going full throttle in a tunnel,sounds so mean like a ferrari. I love the setup.
