My skid frame hasn't bent enough to touch anything. I have had to replace
all the exhaust except the cat over the last 4 years. I bought the last
piece (the back header) from Parts Place, all the rest from the dealer. I
changed the pieces as they went bad.
With liquid wrench and some care the job wasn't too bad, the cost of the
pipes on the other hand....
