LT4 Exhaust Conversion
Hey guys,
It's exhaust time for my 91 L98.
I have an LT4 exhaust system compliments of forum member Gonzo and I want to put it on the 91.
The mounting however is different from my original 91 system.
What parts do I need to convert it over to the stock LT4 mounting?
Also what mods will need to be done to apply the necessary parts to mount this system?
Anybody got any pictures of the mounting with the two "cross straps" that are attached to this exhaust?
Is the LT4 exhaust same as the LT1 exhaust?

i heard the LT4 exhaust is the same as the LT-1 except with one difference, there is a crossover tube by the rear spare tire tray area.
Someone correct me if im wrong.

Here are three pages out of an LT1 manual showing the system as its mounted under the car:

Yes it is the same exact hangers for a LT4, other than the cross over behind the resonator in all other aspects the hardware for hanging the system is the same. Glad to have helped out!
