Hopefully I didn't screw up..

So I ordered some parts a few days ago, one being a pair of flowmaster 40 series delta flow mufflers. I noticed I ordered 2.5 in and out. Is this correct, or will it be compatible with our car?

Depends on if you're only swapping out the mufflers on the stock system. I think the stock pipe diameter is 2.25... but I know on the Stillen CBE, it varies between 2.5 and 2.25

That's all that I'm doing.. Just swapping out the mufflers and removing the resonators and running 2.5 inch pipe in place of them.. So should I be in the clear?

Even if the piping is 2.25", just get two 2.5" to 2.25" reducer pipes and have them weld them to the back of the mufflers then weld the piping to that.

No worries.
