Everybody makes a y kit - But they use resonators. So most go custom and replace with high flows to pass emissions. I had the Pacesetter Y kit.

 

I was thinking about going the route that you did Jbrew. Just order pasesetters and some HF maggie cat and have a shop throw in together. But I was not sure of what the final price would be. Hell total the whole thing ended up costing me around $2,500 in the end. But O well, its done and I am for the most part happy with it and the truck is making alot more power then what it did before.
