name these headers

Since I have my engine out I thought I would put some pictures of my headers on here to see if anyone can fill me in on what they are. They fit my sbc. By the way that's a 3" collector that all the pipes go into then the 3" bends

Re: name these headers

Those are tri-y headers. They have good scavenging characteristics. I have a set on my '69 Camaro, made by Doug Thorley.

As for the manufacturer of yours..... do they have anything on them like numbers or manufacturer identification plate?

Re: name these headers

Alright, now I know, these fit in my chevy K10 truck since I added a 6" extension in the collector before the bend. Plus I went another 3' before putting 2 1/2" mufflers, now I have to wait for my stuff from the machine shop.

Re: name these headers

These are actually FlowTech Afterburner Turbo Chamber headers and they are still available for sale (not mine though)

Re: name these headers

Did you already know the answer and you were quizzing us, or did you find something stamped on them?

FlowTech's Afterburner Headers are the latest innovation in header technology! The patented Velocity Turbo Chamber gives you more HP and torque by smoothing out exhaust pulses which in turn increases scavenging, improving your exhaust systems efficiency! Perfect for most Small Block Chevy applications, the Afterburner Headers utilize a 1.625'' primary tube with a 3'' collector giving you the torque of a Tri-Y style header with the midrange and high end HP of large tube headers!

Re: name these headers

A true "Tri Y" would be 2 primary Y's in to one collector Y.

These Flowtech headers are more gimmick than anything since only one primary pipe is not connected with the other 3 at the collector. But they will still scavenge exhaust fairly decent. Wouldn't be my choice for a header though.

Doug Thorley makes some great true "Tri-Y' headers.

Re: name these headers

John, I spent 2 hrs looking for those right after Sparks post! I remember them from about 15 years ago. Couldn't remember FlowTech made them or what they called them. They really didn't catch on and I figured they had been discontinued. I think Gary is right on try y headers though. If you notice the primary tubes go into two secondary tubes (two Ys) then those two secondary tubes go together into the collector (3rd Y) thus try Y And even though they were a bit if a gimmick, they beat those stock exhaust manifolds.all to heck.

Re: name these headers

I hear ya Mark. Tri-y's were all the rage back in the day. I installed a set of Doug Thorley tri-y's on my '69 Camaro about 8 years ago. Really nice quality, fit was average, one tube hit the pitman arm. They sound awesome paired with the Purple Hornie header mufflers. Surprisingly they aren't that loud when cruising at highway speeds.
