Borla X-pipe: 60547 or 60548?
Am I right in the 547 bypasses the secondary cats and the 548 works in conjunction with? Just want to know which to order. No worries with emissions here in Illinois. Thanks for any help!

So the 547 is the most common choice for the Z06 that maintains the NPP correct?

Just finished installing my Borla X-Pipe (catless) an hour ago. Took about 1 hour on my 4 post lift. The Borlas are high quality construction. I took it for about a 50 mile drive. Honestly, I am a little underwhelmed by the sound. Really not much of a difference from stock except at higher RPM's. Louder at higher RPM's than stock. Of course it's cold here today, 35 degrees, so I couldn't really flog it. I guess I was hoping for more, as I've always liked loud exhaust. I had been driving around in exhaust open mode and even pulled the fuse to keep it open at all times. A little disappointed.
At least it's lighter and flows better than stock. Putting on the Mammo Ported Throttle Body later today.

Just IM Josh. You'll save a little bank and your neighbor will still get a quality price and not have to order it.
