My Car is so loud! I have replaced the muffler system from the catalytic converter to the tail pipe, a soloniod on the side of the motor & a blower of some kind. All parts of the exhaust system. My check engine light is on keeps coming back ( when tested with a hand held tester) with codes related to the exhaust system I don’t think there are many more items to change. The vehicle got so much louder after I had the new muffler etc put on & the longer I drive it at one time the louder it gets!!
Any ideas to make the noise stop?? Please!
Sorry if this isn’t to clear.
