The y pipe fit fine but you have to put it on before you tighten down the headers or it wont go on all the way. No cats. I have the headers then the ypipe and the muffler slid right on the end of the y-pipe. I ran it like that for a while but it was impossibly loud. I went down to oreillys and got an 18 inch piece of pipe and slid it on to the end of the muffler. I just run it like that now. Btw everything is 3 inch. It's kinda loud but it's pretty quiet on the highway. If I ever pipe it to the back I'll just put a splitter after the muffler and run "fake" duals. I guarantee if you pipe it all the way to the back it won't be too loud on the inside of the truck. This video was taken with a phone so it's not high quality. But you get the jist of it. I got the xr-1 part number 40943. It sounds so mean you wont regret it. http://www.youtube.com/watch?v=QFWRkuIP1KA

Just a little but just cause its dumped right under the cab. I'm gonna pipe it to the back and that should eliminate all of it.. I wanted it to scream at wot but be quiet during normal driving and that's pretty much what it is. I get all kinds of compliments from it. Go big or go home!

Not trying to steal your thread. I just have a fast question. I have a 99 4.6 4x4 auto trans. If I do a 3" body liftvshould I be able to fit some long tube headers or will I still run into other problems?

I had pro xs on my other truck and you couldn't even hear it. It still sounded good but it wasn't quite as mean it was a little smoother sounding instead of a growl like the xr-1. Course I still had all the cats. I know that one didn't have any drone at all. I'm fully convinced that pipes to the back would make it much quieter. Borla does a good job of muffling the noise. You can't go wrong with either one
