Yeah I remember reading years ago on LS1tech that it was a design feature on the early LT/LS engines so it never caused any harm to them. Always loved 4th gen F bodies.
In other news going to get the resonators removed finally on my cl55 but not sure whether to do the secondary cats at the same time? I don't want to pay for exhaust work and find out the cars still too quiet thus needing to pay again to have the cats removed and I'm not wanting to remove the cats at the same time incase it's too loud....what the hell do I do. Resonators will be getting replaced with a 3" X pipe.
Watched a hundred youtube videos trying to guess the sound but they all suck due to shitty phone mics.
