Can anybody advise. They make mine from the factory that are extremely quiet and I would like to make some changes. I have put exhaust in the search field and got back every known thought for every known LS1. I have been advised that HSV VY11 have good headers. Can you help me in the following:
1. Are the headers in the VY11 sufficient
2. Change from the Cats-back only
3. Suggestions?
