This was for a 2003 Ford F150 with the 4.6L engine. The piece fit o.k. the factory bend on the "Y" part of the pipe was a little too much and the finished fit has a little angle to it....not a huge deal. The only real issue on this one was the end of the assembly that went to the muffler had the same diameter as the muffler pipe. I ended up cutting notches in the end of the new assembly so I could squeeze the pipe and make it just a little smaller that way it would fit into the muffler pipe. All in all I am happy with the purchase and would definitely buy it again for that price. I little patience during the install and it will fit.
