- 2-1/2 to 2-inch collector/reducer cones
- All necessary gaskets
- All mounting hardware

Additional Notes:
- 1965-1968 Mustangs equipped with power steering require a slave cylinder lowering bracket (SCB).
- Vehicles with Larger Bell Housings may need to slightly dimple the header pipe or remove material on the Bell Housing for Header Clearance.
- Vehicles with a 164-Tooth Bell Housings may need to slightly dimple the header pipe or remove material on the Bell Housing for Header Clearance.

Tech Tips:
- Installation of these direct-fit replacements requires removing your previous headers and replacing them with your new pair of Scott Drake Tri-Y headers.
- 1964-1965 V8 mounts hold the engine approximately 1/4 inches lower that the mounts for 1966 Mustangs and up. You may have to shim your engine up (especially if the mounts are older and collapsed) in order to gain more shock tower clearance. It’s very unlikely that you would have to do this, but it can be done with some washers.

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.
