Anyone used this, particularly on a stock engine? I realize it isn't a popular choice, but I have a brand-new one sitting around that I got as partial trade for parts still attached to my old my Z. I wouldn't have purchased this, as eventually the car will have lt's on it, but I've been toying with tossing it on in place of the stocker while the car is still being daily driven. A search didn't yield any results, but I'd imagine it might be a slight improvement over the restrictive compression-bent y-pipe and stock converter. I am in an e-check county of Ohio, by the way.

 

I have this on my car. I didnt get it with a cat on it. I bought it from a guy on craigslist, then bought a high flow magnaflow cat. Honestly its not much quieter than a hollowed out cat on the stock ypipe. Much better than a stock catted y.
