Majority of custom stuff is rubbish, made as quickly and easily as possible for maximum profit.How do you feel when you go on car forums and see someone’s pictures of their new custom exhaust but all you see is a load of pre-formed pipes routed here, there and everywhere because the builder doesn’t have a pipe mandrel?
I get them off a local engineering company, most of the suppliers here don't seem interested in dealing with small orders.Where are you buying the dairy bends here Anto ? Reynolds ?

Most of my fittings come from the uk, I buy a lot of pipe off of Ebay. For stuff like a 500mm length of 10mm od 8mm id stainless or aluminium pipe for hose fittings on tanks, it's cheaper than anywhere I can find local. If they haven't got it in stock it's buy a full length and wait for when ever their delivery is or get stuffed.True, which is why i buy most stuff i want mail order from the uk.
Turbo or NA
You have to be a lot more careful with NA carbed stuff especially, you'll definitely need your carbs retuned after any sort of exhaust modification.All 50’s to late 70’s
There all on carbs due to pre 63 fia rules but exhausts are mostly a pair of dual 3-1 then a massive dual silencer for noise regs here and abroad

When I got this saw I built a table for it to run vertical but I could never get it to work well. Used horizontal the saw is perfect, never throws a blade, never breaks a blade blade and cuts perfectly square, used vertically it just wants to jump the blade off constantly. I decided not to mess around any more with trying to get it to run vertical as I had it dialed in as close to perfect as I could for horizontal and didn't want to ruin that. After watching videos of people using your method to do it in a vertical bandsaw I've been on the lookout for one, unfortunately vertical metal cutting bandsaws are like hens teeth in Ireland. I recently missed out on this one.keep up the good work anto.
ive a tip for you though, to save you time and work - what your doing is no problem, but you seem to be doing an aweful lot of measuring, and cutting the pipe that way will tend to bow the blade, especially starting on a bend which im sure you found was a nightmare.
do you have a stiff vertical setup for your bandsaw?
i primarily do a lot of thin wall SS and inconel manifolds for race cars, and with that of course is loads of collectors that ive to cut similar to what you are doing.
you will get better results, less blade wear and fast by ssetting your bandsaw up vertical, and feeding the tube in from the end of the tube first up to the bend (oposite to the way you are cutting)
i have simple jigs made up on a feed plate for different diameter tubes, pop them in the jog on the plate, lock it in place, and feed it into the blade from the open end.
worth thinking about
Yeah it is very time consuming doing it this way, I stay away from manifolds for this exact reason, I don't have an efficient way of doing this type of joint as of yet. I do plan on getting something more suitable for this type of cut but until then this is the best I can do with what I haveThere is nothing wrong with what you are doing, it just sounds very time and labour intensive - but i guess if you're not doing it all the time as a living there is no problem with that either
