Product Description

Scott Drake Stainless Steel Tri-Y Headers for 1965-1968 Mustangs with 289 and 302 Engines.

New from Scott Drake are these stainless steel Tri-Y Headers. Over 40 years of Mustang modifications have resulted in endless configurations and drivetrain combinations, but we believe this product offers the best overall fit available. All tubes are CNC mandrel bent, then carefully placed in a precision-engineered welding jig for a perfect assembly and fit.

The Tri-Y Headers will fit automatic and manual transmission Mustangs with large and small bell housings. Extra clearance has been provided for various starters and there is no interference with the shock towers. In addition, these headers provide full articulation of the steering assembly without interference.

Unique features included are extra thick 3/8" flanges to prevent warping, metal-composite flange gaskets, 1-1/2" primaries, 1-3/4" secondary's and 2-1/2" Collectors. Reducer cones with gaskets (which taper to 2") and all necessary mounting hardware are provided. Other features include mounting flange bolts that can also be easily accessed.

*Note: Mustangs equipped with power steering require a slave cylinder lowering bracket (SCB).

Scott Drake Tri-Y Headers Stainless Steel 289/302 1965-1968 is rated 3.0 out of 5 by 2.
Rated 1 out of 5 by from Worst Headers I've Ever Owned These headers hit everything they were supposed to clear. They hit the shock towers, the bell housing, the clutch linkage and the pitman arm. I should have returned them when they didn't clear the first obstacle, but I made small modifications to get them to clear and I figured they were non-returnable after this, so I continued on. After being able to bolt both sides on the engine, I discovered I could not steer the car to the left, as the left header came down right beside the pitman arm with almost no clearance. I wasted three weeks of my life beating, banging, heating with a torch and bending just to get the header to clear enough to be able to steer the car to the left. I tried to salvage this header because I cannot afford to waste the money I paid for these. I can't believe that the person writing the description considers these headers to fit the application. I always had good luck with Scott Drake parts, but this was a BIG letdown for me and I will NEVER buy any Scott Drake exhaust parts again and I will NEVER recommend them to anyone.

Product Questions


Do they fit a 68 cougar with a 302 & power steering?

Asked by: David510
Not 100% sure - while the Mustang and Cougar are very close mechanically, we haven't tried this one on a Cougar to know if it fits the same. Your specs are right - it fits that engine, and works with power steering (if you use a slave cylinder lowering bracket (CJ part #SCB))

Planning to put a 302 V8 into my '65 Mustang conv. I'm considering using the Tri-Y headers, but could also go with traditional long tube headers (Hedman or Flowtech). Which type will sound better? What is recommended to avoid any clearance issues?

Asked by: scotta
Unfortunately, we don't have sound clips for any of our classic Mustang headers, so we can't comment on your sound question - plus, "better" is such a relative term - what you judge as better might be the exact opposite of my opinion. Regarding fitment: I'd recommend reading the product descriptions on the ones you're interested in. We usually list any fitment restrictions or clearance issues. there.

As these headers have a 2-1/2" to 2" reducing cone, will they work with a 2-1/4" or 2-1/2" exhaust system?

Asked by: Kesman
I just ordered a set of these headers and I plan to put the reducer into my 2-1/2" exhaust pipe, draw a line with a Sharpie on the reducer where they touch and cut, then just butt weld the two pipes and I'm in business.

will these fit a 65 falcon sprint with T-10 4sp

Asked by: old guy
Unsure. The CJ's team and the manufacturer have only tested this product for the fitments listed, so anything outside of that, we can't comment on. It could work, but that's something you'd have to figure out for yourself.

Scott Drake Tri-Y Headers Stainless Steel 289/302 1965-1968 Video Transcript
By Bill Tumas: Bill from CJ's here with Scott Drake, who's going to tell us a little bit about his Stainless Steel Headers.

Scott Drake: Thanks, Bill. These are '65-'68 stainless steel modified Tri-Y headers. They fit all small blocks. I'm super proud of this part, because we've had the car up and down on stands multiple times, adjusting, tweaking, this, that, the other thing. It will work on cars with small bell housings, big bell housings, the T5 conversions, manual transmission cars, power steering cars. So it's a tight fit on some of those combinations, but we tried to produce a product that would fit all applications, and really that's the trick. This example is a 304 stainless, which will never rust. But we also sell them in black high-temp paint, and soon to be ceramic-coated headers, but they're not quite available yet, but they're coming soon. The features and benefits of this is a really thick flange, stainless steel construction, a good flow with proper clearances as I talked about before. Also includes and exhaust manifold gasket, American standard threads on the bolts, the flange, a reducer cone, and the bolts. You just got to bring it to your muffler shop, hook up your exhaust, and you're ready to go.
