I'm attempting to replace the muffler/tailpipe on my 03 Blazer, I ordered.Walker #55031 tail pipe and Walker #18934. Never really worked on exhaust before, so I assumed all I would need is a clamp to join the two together since the Walker info sheet on Rock Auto only mentions a clamp is necessary. https://www.rockauto.com/en/moreinfo...411995&jsn=452 When I got the parts I measured each opening and the muffler outlet was slightly larger than 2 1/4" and the tail pipe was right around 2 1/4". So I figured that I could just insert the tailpipe into the muffler, clamp it and call it a day. But the pieces didn't fit together well, so I used vice grips to try to flare out the end of the muffler outlet. Didn't really work that well, could only insert tailpipe about 1/2". What am I doing wrong here?

 

Go to auto zone and rent a tail pip expander use it to expand whichever female end is too small

 

I ended up doing exactly this. I was hesitant at first because all the reviews I saw online said that this wasn't possible, that the tool was only for restoring the roundness of the pipe. Ended up working perfectly and the exhaust is fully replaced.

 

Excellent glad it worked out for you
