Ok so I got my car back from the dealership today after not being able to get it to fire. Turned out to be some fouled plugs and they replaced em and sent me on my way (5th set of plugs now btw). Now here is where it gets weird. The car is quieter, way quieter! I have the 3" AA exhaust and it has always been anything but quiet. It sounds like a stock exhaust now. I looked under the car and the exhaust is still there. There is NO WAY this could have been them just tightening up the exhaust. It also has a very bad hesitation under acceleration now. My only thought is maybe the cat is clogged? Will a cat clog that fricken fast though? Like literally in one day?
