I have the engine and dual cat exhaust out of the car.
The car currently has Hotchkis SFC's which interfered with the factory dual cats. I am going to cut out the Hotckis parts and install Spohn's version.
-I purchased a SLP header package with Random Tech cats.
Anyone see any problems running the dual cat SLP setup with an LT1? I hope not since I already bought the stuff

 

Ok, maybe I wasn't clear enough.

Has anyone done the LT1 swap and retained the dual cats?
If so were there any problems?

 

There shouldn't be any problems at all. The only difference between an LT1 and a regular small block Chevy is above the heads, so it should be fine.
