Astro Tools Exhaust Stretcher Vs. Stainless Steel Exhaust Pipe

[@orickbriscoe5641]

Do you think heating up the pipe with a blow torch a little would help with the process?

[@ChallengeTheBuild]

Yes it would help but then the concern with the heat would be melting the rubber bands of the expander.

[@cayankeelord3730]

Maybe once the tool has expanded the pipe, before releasing the pressure, going around the expanded area with a hammer and giving it a bunch of light blows would help to set the expansion by relieving the stress of the metal. I've seen a lot of folks here on youtube convert these to hydraulic. The only concern would be ripping the threads off the draw stud or nut. Everything has it's limits.

I would like to convert this to hydraulic at some point...I appreciate you watching and commenting. 👍

Stainless will not stretch like mild steel. Even a professional muffler spreader will crack or rip the stainless.

You need to use a torque-bar not an electronic wrench.. it doesn't have the power you need.

[@ChallengeTheBuild]

So using a torque bar / breaker bar is difficult because of how much force you need to clamp down on the pipe to keep ot from spinning. Not that it isn't doable just adds a little bit more difficulty to the job...

Don’t you have Air in your Shop

[@ChallengeTheBuild]

I do... Limited air tools... Anymore I opt for battery... No more air hose, however there are some tools that just need to be air powered!

[@tonyzook4064]

I have the same kit, and use my air impact gun piece of cake, don’t know why you didn’t use air

[@ChallengeTheBuild]

Gave me a reason to buy a Milwaukee 2767 1/2" Impact 😂😂😂

[@bccoregon]

The Milwaukie actually has more power than our air impact guns. This is our experience in our shop.
