Thanks for all the input here everyone. Exactly why I come here.. so long story short, maybe some sound improvements, but no hp gains without a tune.. fair enough!

correct just delete your rear cats or do a axle back. Headers or just hi flow cats require a tune and you already have shorty headers. GM can cancel your warranty just seeing you illegally removed your stock cats. Want to fight it in court. You removed emissions components so you loose. Even if the component you replaced didnt cause a the failure you will have to fight it in court for years and thousands of dollars. you want to keep warranty dont touch cats forward. rear cats wont void warranty though as a cat back will not. Rear cats are a commiforia thing.

Camaro has shorty Tri-Y OEM headers. Stay stock until you want to tune.
