Regarding the "H" pipe found on the exhust system of the 5.0 powered 1987 (and later) Mustang:
There are four chambers in the factory-made "H" pipe, the two at the rear are convertors. Are the two at the front of the "H" pipe also convertors or are they empty EXPENSION CHAMBERS?
I bought a used "H" pipe at a performance swap meet (mistake #1, due to the nature of the swap meet the pipe probably didn't come from an unmodified (i.e. running overly rich engine). Within eight months the convertors were so clogged with carbon that the engine would barely run.
Upon expecting the "H" pipe I find that the front chambers are empty and am trying to figure out if the last owner had removed the packing (if they are convertors) or if the chambers are simple expension chambers.
(Note: If you are thinking of installing an "Off Road" "H" pipe on a street driven car, DON'T! That was my mistake #2. The resulting increase in exhust noise isn't worth it as it is quite loud. It's almost as bad as having header mufflers that end directly below the seat!)
