They are alright, I'm having some issues with Check Engine Light popping up and P0133 and P0030 codes

i used to have a aftermarket muffler that all it did was waste my gas and not let my car respond when i accelerated. now with this new muffler as soon as i tap the gas pedal my car responds by speeding up quicker. as for the in cabin noise there is none which is something i was looking for.
