when i step on my mustang i get a weird noise from under the car....i think i broke my cats it rumble pretty bad......what do u guys think i need help!!!!!!!!!!!?

 

Might want to be more specific. Try going into detail.

 

Why did you post 2 times?Give a little more info and give some time for ppl to replay.

 

I would say crawl under/look under your car to see if you have any pipes hanging down. Is this noise there all the time? Or just when you accelerate? When did u notice the noise? Have you done any exhaust mods? Just a few questions that will help us figure out whats wrong.

 

like when i gun it, it feels like its not letting it breath i dont know what it is like it sounds bubblely like a subaru....i think i broke a cat since its throwing alot of more exhaust since its supercharged....what do u think?

 

yea its sounds louder when i accelerate......i already checked under the car....everything on good.....it started sounding like that after i gun it.......i dont think its the motor cause the motor has no motor noise and its running good

 

Well you really cant break a cat. You can break the pipe leading to or from the cat. But cats dont break per say. How long has your car been supercharged? Did you change your exhaust set up? Could it be an exhaust leak?

 

its been supercharged for about 8 months now......i have a magnaflow exhaust on it.....i just feels like its struggling to let out the exhaust....... i dont think its the motor cause its runs good and theres no engine noise......what do u think?

 

Again man, you have to provide some more information or else no one can help you. If you can't do that, just take it to the shop and let them figure it out.

 

read the replys i gave alot of information!!!!!!!!!!!!!!
