Hey I got a question for anyone that has installed BBK headers. What size are the Pipes on the BBK High Flow cats that your Cat back would bolt up to? Just wondering if a LS3 Stock exhaust (2.5 inch) can still slip over the Cats.
Edit: The Stock LLT Pipes are 2.5 Pipes in the begging and then change to a 2.25 after the H-pipe right.
