Replacement of stock exhaust dampers with KOOKS

[EF300]

A recently developed a crack in the drivers and passenger side headers requiring replacement. I am suspicious that damaged exhaust dampers contributed to the failure. The dampers cannot be ordered from Ford. They will only sell them as a part of the catalytic converter assembly whick is $1000+


So, I saw that Kooks made a damper assembly 4 there GT 350 Exhaust. The part number is 1154 DKIT. The cost is $40 The Kooks kit comes with 2 aluminum dampers, a bolt / nut and 2 rubber gaskets.


The kooks set up weighs 13.15 oz. The half of the factory damper I have left weights 7.2 oz so x 2 that and its pretty close to the stock set up.


I have included some pics of other measurements for reference.


All in all this seems very close to stock.


Install is a direct swap. You can unbolt the factory set up with a 15 mm box wrench and just bolt up the Kooks Damper. I used some red loctite on the bolt to be safe.

I thought you were doing the buyback? Why spent money?

 

[EF300]

I am having issues with a buy back b/c I have had my car for more than 2 yrs. So far ford has not agreed to a buy back. Per my lemon law 2 years in the max for a claim. I may be able to do it under magnuson moss act but gonna need a lawyer.

I use the Kooks dampers and am pleased with them. They’re local to me and good to work with.
