96 cobra new exhaust do I need to tune?

[coops96cobra]

I just bought a flowmaster outlaw catback exhaust system and heard I could get spark lock without a tune, is this true if so can I tune it myself with a macbook? Thanks for your time and effort

No tune required.

I don't know where you heard you need a tune with any catback exhaust, but you do not. Regarding exhaust, only long tube headers and removing your cats requires anything in a tune to be changed.
