Can anyone help diagnose my smoking problem? I have MHD stage 2+ muffler delete, secondary resonators deleted, and a downpipe. I ordered a oil catch can but yet to install. Details are the car doesn't smoke until it warms up and only notice it if I rev passed 4k rpm then on deceleration it puffs blue smoke

Some smoke is going to be normal since you deleted the cats. But if it's a ridiculous amount of smoke then there's an issue. Video maybe?

Upfront if there's an issue, it could be the turbos as smoking is a sign that they are on their way out. Is oil leaking past your seals? You could see this from under the car.

Is the smoke sweet smelling? That means coolant is leaking into the engine and burning which could spell bigger issues.
