Best Company To Buy Stainless Turbo Piping From?

[Rick Giles]

Can anyone tell me, hopefully from experience, where to buy stainless turbo piping from? Just bought an unfinished project that needs piping from 2 turbos to 2 intercoolers.

Most of the normal stuff we do, Stainless Works offwea very nice bends at a reasonable price. We use these on most of our turbo header builds.

If you need the nicest quality available, then SPD or Burns Stainless would be your next option but, more expensive.

What about McMaster Carr. They used to sell 304SS tubing. I know a friens of mine used MC on his turbo Mustang.

Another option, a little spendy, but nice stuff.

I don't know if you are set on stainless but aluminum is a common thing when it comes to intake piping. you can find plenty of kits on fee bay they come with 2 90s 2 45s 2 straights 2 180s and couplers for about 120 bucks.stainless can be used but great care must be used for it is very easily warped and when you weld the outside the inside should be purged with argon to prevent sugaring of the inside of the piping.just my 2 cents worth.good luck with whatever you decide.

Thanks guys! That is all good info. I think stainless would look the best since the hot side is already done in stainless.

FWIW Aluminum should also be purged with argon on the inside of the pipe. Mild steel piping is pretty much the only thing that should be welded without a inert gas shielding the other side of the weld.

Burns, SPD, and Woolf Aircraft all make very high quality stuff. I used SPD and Woolf for my 321 stainless up-pipes to the turbos, the 321 wastegate tubing, and 304 stainless downpipes. Their bend quality is superb!

Woolf also offers some very tight 1D radius bends that the other guys do not offer, so keep that in mind if you have a "tight spot."

For the remainder of the exhaust from the downpipes back to the mufflers I bought all the 304 stainless bends and hardware from Columbia River. While the tubing is good quality their bends aren't quite as nice as Woolf, SPD, or Burns. They're not crushed, wrinkled, or rippled, but expect a few minor die marks and lots of grease left inside from the forming mandrel. Columbia River's stuff is not as pretty as the "high dollar" guys but for the exhaust under the car it's plenty good in my opinion and substantially cheaper. Don't get me wrong, CR's bends are still nice but they are not as perfect as SPD, Woolf, or Burns. The straight tubing itself that CR uses has Made in USA ink stamps on it-- so that's good!

FYI, if you're building tubing from the turbo outlets to the intercooler I would recommend using aluminum. It has a much higher thermal conductivity than stainless and will "shed heat" from the hot air leaving the turbos more effectively than stainless which has a much lower thermal conductivity and tends to keep the heat in.

As mentioned, remember all the necessary welding procedures for stainless tubing. Tungsten size, heat range, backside shielding (flux or backpurging), etc. A poor stainless weld is very brittle and an overheated stainless weld is also susceptible to corrosion.

Thanks for the help! Aluminum does sound like a good choice now.
