Exhaust Expanders

Ok, need to pop a collector to mid pipe open about 0.5 to 1mm. Is stainless.

So am I wasting my time reaching fr an expander off of ebay. What sort of luck am I going to get and should i be aiming to get it Reall fackin hot??

This is one of those times where I may need a grown up to make me a custom link pipe, but I may be able to get what I have working.

Don’t bother with those eBay hobbies, especially for stainless.

Try a tapered piece and ram it in hard! (Turn a former and press it in to expand)

or cut and reweld in a taper.

Is that like the China eBay type? Either way for what you want it should work, just change the bolt for a non chocolate based bolt, and if you heat it then obviously the o-rings are disposable, just get it biting before you warm it up.

That is very good of you kind sir. Much as my interest has been piqued by some of the suggestions on here, I might die of shame if it was lurking around forever. 

:P

What would be interesting is if it was an older well made tool, in which case I'll borrow it.

If it's a similar design to whats currently available on that there site for 15 squids, I may as well just buy a kit..

Also the current plan will probably involve a Hi-T bolt swap in and some windy gun action to concentrate the material to do as it's fuckin told.

This may end up with a damaged tool, so. you have been warned not to let it anywhere near my offending orifice.

:lol:

The cheap ones can and will break even without said windy gun, but they can do the job.  Best to have two on hand (and extra o-rings just in case) and take a fairly incremental approach to it.

 

 

 

We are talking about butt plugs still, right?
