Is this risky?
Is this risky? I just had longtubes installed with a catted-y. No O2 sims though. I am gona get a tune in about a month, and of course wipe out the codes, but untill then is it safe to drive around the car? Are there gona be any negative side effects becides the check engine light? This car is NOT my daily driver so it wont get driven much

yup... no problems driving... rear O2s are emissions only, won't affect performance... the headers will lean you out some but most likely not enough to grenade anything... people were putting long tubes on these cars long before any aftermarket tuning solutions... for the most part you're just giving up power
However... reading your sig... the hypertech tuning (leans out) combined with headers could pose a problem... I would remove the hypertech tuning (you'll want to remove before you get the car tuned anyways so the tuner can start with a stock file)
Don't see anything about ported MAF or aftermarket MAF so unlikely you'd go lean enough to harm anything (with hpp3 programming removed assuming you currently have the "performance tune")
