I currently have the Bassani X-pipe with cats. Its the newer style where you can swap the cats for straight pipes. The x-pipe sound never quite grew on me. I would be willing to do a straight swap with someone that has a catted h-pipe. Or I will swap with someone that has an offroad h-pipe with a little cash involved. You can email me at [email protected]. I am located in Santa Barbara, but travel to the LA area frequently.
