I bought a car with the hanger completely missing and I used 2 stainless steel hose clamps (the super large ones) to hold up the exhaust to the cross member; when I installed the Hooker system. It was a temporary measure until I could come up with something permanent, turned out that was 5 years ago....Guess it worked, no one really sees under there, and I never got around to it.
IMO its best to have some kind of support there it is pretty heavy.
I haven't had one in 15 years.hello; IMO you need all the support espesially if you have a dual muff system. I had one and put an extra support besides the hanger as the system weighed alot. Depends on what system is there now about the lowness of it but if it was me I'd do something there to add support.
