Patriot Exhaust Tri-Y Headers Ceramic-Coated 260/289/302 1965-1970 is rated 2.8 out of 5 by 6.
Rated 4 out of 5 by from Good headers for the money Headers fit well relative to shock towers once I solved a motor mount problem. Driver side header contacts steering linkage (manual) and had to dimple which cracked the ceramic finish. (Reason for the 4 vice 5 rating.) Good finish otherwise. Collector reducer is 2.5 to 2.25. Had to buy different collector reducer. (In retrospect I should have bought 2.25 system vice 2 inch.) Lines up well with CJ's tri y h-pipe (EXHP23) with only minor reducer cutting needed. All in all, Pertronix makes a good product but I think I would have liked the Drake stainless tri y a bit more in this price range.

Rated 5 out of 5 by from Fit like a glove, look great These fit like a glove in my 5.0 in my 67 with C4. I installed from the top and they just drop right in, very easy install. It does come very, very close to the starter (nearly touches it), so I put a heat shield around the starter. I've had no problems with starter heat soak. The finish on them looks great, after a summer of drive time it's still holding up well.

Rated 1 out of 5 by from Poor Fit Bad fit, Hit shock towers, bell housing and clutch release arm...I should have sent them back right away. But, thought a minor mod would do the trick. One mod led to another....now its embarrassing ! This is on a restored 65 Fastback, beautiful car except the headers...I will prob junk them soon. Any one want a set cheap ?

Rated 1 out of 5 by from Horrible, Horrible, Horrible!! I purchased these in 2012, within 2 years they started rusting and cracked. I have always kept my Mustang in the garage. I called the company and they said the only thing they could do for me is sell me another set at cost. I would not recommend these to anyone!!

Rated 4 out of 5 by from Fit Well Fit very well on my 302 Block, but took a little work to line up with the rest of my exhaust (Flowmaster Dual Exhaust Kit American Thunder 2-1/2" With Turndowns Coupe/Fastback V8 1967-1970). Throttle response is much better as a result.

Rated 2 out of 5 by from Does not fit a 1970 302 with a manual transmission Will not fit a 1970 Mustang with a 302 and a manual transmission. Does not clear the clutch z-bar and hits the starter. Quality of the product and workmanship is excellent just doesn't fit a manual transmission.

Product Questions

I like the headers you are advertising but because I am in Australia I just wanted to 100% certain that these will fit my car, it is still left hand drive and no power steer. can you provide a price landed Brisbane

Asked by: Rowdie
Unfortunately I cannot accurately answer your question. Without the vendor supplying any information regarding fitment for non-US Spec cars and CJ's not having a car to test parts on, we cannot confirm this part working on your vehicle at this time.
