before all of this my car actually had around 310 to the wheels it was an animal thats why i decided to have the car tuned , because the car felt very slow.

Thats BS. The cats can in fact clog. My friends 2000 truck had one that was clogged. It was performing so bad going from a stop to 60 took at least 15 seconds, if not more. Oddly enough though, it wasn't throwing a code and we couldn't figure it out. We checked everything, fuel filter, air filter, MAF, even if it had bad gas. Nothing was wrong and I figured if it was a cat it would through a code. Well it didn't. Hell, the mechanic he took it to couldn't figure it out. The ended up charging him $800 to replace the fuel pump when it was acting up before he ever got out the parking lot with it...So it IS possible...

The car is quiet as can be no drivetrain noise.

I doubt thats the case since he said it felt really slow.
