The other week when I was installing them, I noticed that the back of the Y looked like it was meant to slip into the stock piping to the mufflers. I couldn't get it to work at all. Am I wrong in thinking that's what's supposed to be?

I don't want to pay to get it welded if I don't have to, but I couldn't get it together and I ended up pulling my exhaust all the way off.

im not sure, i have a 3" flowmaster catback (american thunder series) and it was a pain to slip the y pipe into but i eventually got it

You can't even weld mild steel to SS. So how do I do this? I spent a long time trying to get it together and an extra few hours just pulling the stupid catback.

It would be a HUGE headache to get the catback back in place just to find out it won't go on.

I could cut off the straight portion of the pipe and slip it on then get the rest of the catback welded on later.

But I want to skip welding altogether. What a headache.

i actually had to use one of those pipe spreaders for the catback i think...i cant remember exactly how i had to do it but i remember that part took me a good couple of hours to figure out what to do and get it in

The back of the LPP is intended to merge into the stock pipes. Most will cut that reducer off and create a small intermediate pipe that can be expanded by any muffler shop. Or you can simply expand the LPP pipe once the reducer is cut off.
