97 t100 exhaust help plz!
Hello Everyone and thank you for your help in advance…
I have this truck and the catalytic converter was cut off and replaced with pipe and the muffler is entirely rotted out as well as the latter half of the pipe. It is very loud in the weld job on the catalytic replacement was crap so it smells like exhaust in the cab all the time. With worry about lack of back pressure, my first Question is,
1.Can a person replace the catalectic area of the exhaust with say a smaller size pipe (from 2.25 to say 1.75-2) to create some pressure? So the exhaust from manifold to catalytic to muffler would look like this (Legend):
:: manifold
= pipe
~smaller pipe
#muffler
::==~==#==
AND Question 2(a,b &c):
if this is no a feasible or safe/etcetera solution, (a)How do I assess whether or not the missing catalectic has already caused engine damage and if it’s not that easy to diagnose, (b)how do I determine if it is worth replacing the exhaust, in it’s entirety (catalytic/pipe n muffler ~$300) or (c) leaving it (after I repair the holes) straight piped?
