how to expand an exhaust pipe?
I got my side pipes back from Jet-Hot and one of the tubes is bent at the flange and wont slip over the header pipe. The tube is bent at 2 spots, so it isnt and exact circle any more. I saw summit had a "tailpipe expander" but only expands to 3 7/8". Anyone have any ideas??
Thanks
Chris

Exhaust shops work with 4" or 5" pipe all the time now for diesels. They would have an expander. Shouldn't charge much at all to straighten it.
The hammer's not a bad idea either.

I would think a muffler shop would do it for $5 or less. it would take about a minute

a friend had an expander, but was only meant to go to 3 1/2" but picked up some extra long bolts and got it rigged up to possibly work.... only problem is the threaded rod may break while trying to turn it..... well see what happens tomorrow. If that doesnt work, ill try to bring it to a Midas that i know the owner.

Those expanders can be useful for rounding out a pipe that is the right size, but it is very difficult to actually expand the pipe with one of those things attached to a wrench. At Midas they will have an expander that looks pretty much the same but is powered hydraulically and can turn your 2.5" pipe into 2.75" pipe!! I had a couple done there. MJ

For expanding stainless pipe get an exhaust shop to do it :yesnod:
One more thing: the pipe was supplied (& bent) by a company that make exhaust systems for F1 cars & they told me that the method I was using to anneal the tube prior to attempting to expand it was correct, so it's not like I was trying to expand work hardened metal :(

Chris, Take the pipe to any muffler shop. They can expand the pipe for you. They might charge you 10 or 20 bucks. :thumbs: I'm a welder and thats what I would do if you came to me with it. There price plus 25% or more for me. :hurray: :seeya Steve
