I purchased this part from Performance Nissan Parts. I had them shipped next day air so I could register my new car as soon as possible. The previous owner lived in part of the city that has more relaxed emissions laws. Unfortunately, I must comply. Also, the loudness and rasp of the Stillen test pipes was getting to be too much for me (and I'm sure some of my neighbors). The sound of the nismo exhaust is much more clear now and that's just the way I like it. My mechanic pal Alex who put on the highflow cats already sold my test pipes for me. I would definitely highly recommend ordering from Performance Nissan and for anyone who has test pipes and needs to get rid of the rasp/loudness consider highflow cats from Crawford.

Any gains/loss over stock cats?

Yes, though it's purely from my own butt dyno. I didn't own the car when the original owner went from nismo intake and nismo exhaust to test pipes and plenum. But I could definitely feel a difference in power. I am hoping to get on a dyno soon if I ever decide on a piggy back for my N/A car.

Can you make any sound clips of your car? I would love to see how this combo turns out! Some nice drive by's would be nice. How loud is this combo?

crawford cats for sure gain power over stock - not to mention lose like 20 lbs

they sound identical to stock except louder

Hey, I finally got around to making a short video. The wind noise doesn't help too much, but hopefully you get an idea at the lower speeds what the car sounds like in everday driving.
