Since the Magnaflow Tip # MF35181 is a weld on, you could make it fit. Whenever I weld on pipe or tips to my exhaust I always match the piece I'm adding to the size of the existing pipe. I do this because I can lay down one bead to hold the tip in place, then weld around it. Then, once she's all welded up, I can go back with the grinder and grind down the welds if need be and I'm left with a clean looking connection. I like to keep the connection as seamless and smooth as it can be. I've made a 4 inch pipe work with a 3-3/4 inch pipe before but it didn't look as clean.

So yes, you could make it work but I would suggest getting the same size if it will be easily visible. Be sure to do this in a very ventilated area if at all possible. You don't want to spark the fumes from your gas tank!
