so i was driving my 07 ss/sc to a car show and when i accelerated onto the highway tacking over 4k smoke with a blueish tint poured out of my exhaust between shifts 2nd-4th, I was curious about what the problem can be because it doesnt smoke driving normally or idling or reving. Im so lost as to what is going on.

Car Setup:

Fresh mobile 1 sythetic oil
Injen Air Intake
Stock Tune
Catless 2.5" DP
2.5" Megan Racing Exhaust
NGK irridium Plugs gapped to .035

 

Do a compression and leakdown tests. could have leaky valves or a bad piston ring ETC.

Good luck man.

 

Miles?

 

I'm thinking cause you're catless is one reason. Are you sure it's not BLACK instead of blue? Black is fuel which is normal for these cars.

I took the cat off of mine because I thought it was causing issues and when I give it some gas I get smoke, not a lot but enough to get my attention.

Cat is back on it now and smoke is gone.
