Diesel Exhaust Kit
 

Guys,

I have a 1986 F250 XL Standard Cab 6.9 IDI project truck I am working on.

Current exhaust is the stock 2.5"

I would like to remove and replace with the Dynomax 3" to 4" (Kit Number 19430) Exhaust.

The question I have is was there any difference between the 86 and the 88 from the manifolds back to the rear of the vehicle concerning exhaust system?

The reason I ask is that the Dynomax kit states only fits 88-94 and they have no listing for anything earlier than 1988.

Appreciate any help.

Great site by the way.

It should fit just fine. The 6.9 and 7.3 were just about identical outside.
