i have a loud fart noise comming out of my cat. it started after i got in the wreck whats a simple diagnosis of this im thinking it got jared and a gasket came lose. just looking for an answer im gonna work on it i know its gonna be simple. thanks for whoever replies. Note* its a gutted cat.

 

Why would you gut a cat on a nearly-stock ka? To pollute 4 times more and gain .5hp? Fix your shit.

Your crossmember damage probably shifted your motor. You driveshaft has joints in it to move, but your exhaust doesn't. You probably either broke a bolt, or cracked/broke a flange. Turn the car on, crawl under it to find the leak, repair. That simple. If something is broken, get a new one.

 

you made it pretty obvious you knew exactly what was wrong with it.... go fix it youself... and i agree w/ jeff lol

 

you should just give me that 240, ill make it nice again
