What is this noise?
Can someone tell me what part of my car is making this noise?
RPM when it happens is about 3K. I took it to my mechanic and he said that nothing seems loose. He said the banged on all of it with a hammer and didn't notice anything beside that my motor mounts are shot. Well I made this video and went back there today. They got under the car and said they cant tell it its internal to the muffler or the cat. He said it needs to be on a lift with a bunch of guys under it to diagnose it. It sounds to me like the guts inside the cat are shot... Mechanic says if cat was shot I would be getting engine codes. He says more likely its the main muffler is hallowed because no codes. Anyways, I am sure someone's car on here has had or does have this same rattle. So any advice is appreciated. Last edited by Lookin4SVX; 05-19-2012 at 10:15 PM. |

Sounds like mine did. My resonator was bad. I just had a straight pipe put in to replace it. Cost $40. You can either replace the resonator or just take it out and put in a straight pipe. The straight pipe will give it a little deeper tone, but mines still pretty quite.

Ok, I think I understand why I am confused.
I thought that the "resonator" was another cat... Just to make sure that I am on the same page now.. Am I understanding correctly? |

Re: What is this noise?
That is the correct part. You may want to put some type of resonator in to replace it though. Without it, it will still have a resonant buzzing at certain RPMs. I have driven a car that did not have a resonator and although it sounded better at idle and low throttle, anywhere from about 2500 RPM and up, it was one of the most annoying things i've ever heard.
Just my input on the subject |

Re: What is this noise?
Ok well I am not going to put the OEM part on, that is like $200+.
What aftermarket resonators are we all using? Spadedone, yours have buzzing resonance with no resonator? I don't care if its louder, but I cannot stand this biiiizzzzzzaaaaat sound. Sounds like the local honda street ricer exhaust when I get on it. From 3900-4200 in 2nd when I hammer it, its the most god awful noise. Last edited by Lookin4SVX; 05-19-2012 at 10:16 PM. |

Re: What is this noise?
Use an AR20! They are rasp reducers and make it sound nice. I think they're around $50.00.

Althought the sound is like a really quite fart can on a tuner.
