Vehicle Fitment

This product will fit the following Mustang years:

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 3 out of 5 by from Pretty but Defiantly not Perfect I bought this for my 1966 289 manual. These look and feel nice, even the gaskets that came with it are usable. No interference with the clutch for me. Had some problems getting it to fit, the right side of headers were touching the wall of my engine compartment. Had to pound them a little bit in order for them to fit. Biggest problem is the width of the flange. They hung down so low I couldn't fit a socket on the spark plugs, they were extremely difficult to install because of this. Also it should be mentioned these took 2 phone calls and 3 weeks after I purchased them for them to be at my door. I would try looking around or ordering from another site, but these are good for the price.

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 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 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 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 Uneven outlet to collectors The picture shows the collectors of these headers both coming to a horizontal plane. Unfortunately, on the headers I received and installed the driver side hangs down almost 2" below the passenger side. It looks awful and scrapes over bumps. There was also an interference between the manual steering arm and the down tube as shown by the arrow.

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.

Will they work on GT-40 heads on a 302 from a 1993 Fox Body Cobra Mustang? Will they work on GT-40 head on this 302 installed in 1967 Mustang with a T5Z 5 speed manual transmission; head clearance front-rear: Driver 4 1/2"- 3 1/2"; Passenger 5" - 4 1/2"?

How does this work out with the pitman arm for the steering? We have a '66 Mustang in the shop that the Pitman Arm not only had interference, but actually flattened one of the tubes.

Asked by: KrispyKrisKringle
With long tube headers there can always be clearance issues. This bracket will take care of the slave cylinder clearance. https://www.cjponyparts.com/scott-drake-slave-cylinder-lowering-bracket-1965-1970/p/SCB/

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.
